Scott I think you're missing the fact that you can utilize the spatchcock method along with rotating the turkey while it's descending. You can cook a spatchcock Turkey in less than half the time and if you rotate the bird for equitable heating a 15-30 minute re-entry is less absurd. I feel like this is totally a doable thing if you have a two sided equitable weight capsule where one side has an ablative heatshield and the other has a metal surface. Once it hits a certain temperature the vehicle flips to stop the cooking process. This will also allow the bird to come up to temp appropriately so it will be ready for carving the second it touches down.
I wanna know what happens if you drop in it a steel barrel full of oil and let the ensuing fireball on the ground to cook it the rest of the way through.
How will the vehicle flip once it reaches a certain temperature ?? Will you have to manually program it to flip or is there some existent physics behind it ??

@@Benoit-Pierre nah, you just gotta perforate it with heat conducting spikes. Iron maiden style. Or pressure cook it. (Or both) :-) culinary science can probably come up with a way ;-)
Funnily enough, I remember the textbook for my Thermodynamics class having specific heat values for a bunch of food items (both frozen and room temp food). While I didn’t pick up the values directly I remember that the highest of them were probably 80% the heat capacity of pure water. EDIT: guys wtf did you do to the replies here, I just wanted to make a funny remark about Scott’s comment on the lack of textbook info on food.
What if say you wanted to incinerate turkeys into ash , and the turkeys are oversized (basically human sized) and you say have five or six oven capsules but need to 'cook' six million or so turkeys for thanksgiving or something ? Any idea how long that would take or if it would mathematically be feasible ?
@@pepopipo974 Engineering toolbox has a webpage titled "Food and Foodstuff - Specific Heat". It has the values for turkey there. TH-cam hates people that post links but you'd be able to get there with a quick search.

Agree with above commenter except instead of retracting one point, I give total of -1 points out of 10. That is because of unlabeled axes that also constituted the whole video being one hardly understandable mess. Unless you actually understood the calculations and formulas behind the graphs, there was no way of understanding anything accurately enough. "More time in the orbit" or "less time..." just isn't enough information to be even slightly meaningful.
Attach a valve to the front to regulate the pressure down to 1 atm. It would help with balancing the temperature too! And if you attached it prograde, it would provide a very weak retrograde thruster for you.
When the turkey thermometer pops, it activates the inflatable heat shield. Use a raspberry pi to monitor excess fat to control the centrifuge speed. Gotta say I've scrolled past this a bunch of times, but I'm so glad I finally watched it!

What a stunning example of the engineering thinking process!. All student engineers should see this video, because we are often confronted with strange, undefined problems, and the thinking processes needed to solve these questions are expertly and beautifully demonstrated in this video.
Multiple skip re-entry might be a better option to cook.. repeated exposure to lower and higher temperature across the surface of the turkey might do the trick
Now I’m imagining a orbital food delivery service that de-orbits raw food direct to the home. When it gets to the ground it’ll be perfectly cooked for consumption. Pizza would be a good choice for it’s surface area!

What about jabbing heat conductors into the turkey to accelerate the cooking? The other thing to consider is whether or not turkey is a viable option for heat shield material.
Let's go all in here an do a right job. Instead of simple conductors, let's use heat pipes pumping in molten salt to transfer the heat faster into the turkey to allow is to cook fully in 15 mins. The engineering involved would be insane.......but worth it!
@@surferdude4487 Since we are already going to the expense of launching a turkey into orbit just so we can cook it using re-entry heat, I think we should be thinking BIG! Cost and complexity are no consideration at all and as such I want to change my previous suggestion from molten salt to a Lead/Bismuth eutectic as used in fast spectrum nuclear reactors!!!

@@plasmafoal1117 You seem to misunderstand me. Cost and complexity are not what I'm concerned about at all. I just thought that molten salt would be far too hot for our purposes. The objective is to cook the turkey to perfection, not carbonize it.
@@surferdude4487 you are right of course, molten salt will freeze long before the optimum temperature is reached. I am ashamed and embarrassed that I didn't foresee this issue.

That being said, normal radiator coolant seems to be too straightforward and makes the most sense so we may have to reject it for those two reasons (its straightforward and makes sense). Ammonia is used as a coolant of the ISS and I like ammonia due to the fact we would have to use it in its superfluid state!!! How awesome is that!!! Superfluid Ammonia at high temperatures to cook a turkey on atmospheric reentry sounds like really interesting approach with load of expense and risk!!!
maybe if you change the angle of entry.. the turkey will be skipping several times in and out the entry zone.. so maybe if you can make it skip 20 times in and out the atmosphere, it would be sufficient to stop it from burning and gain in culinary standard.
8:16 These numbers are in tons per square meter because I figure if we got Fahrenheit involved we might as well just try some new interesting new units. Lol
The thing that you didn't talk about is thermal mass. Put the turkey inside a thick cast iron block, or maybe a liquid tank, and have a shutter that allows heat to reach the iron, or a tubes running the liquid through the heat shield, so that you heat up the thermal mass to 500 degrees or whatever, and then you stop adding heat Then you can land the oven, and the cooking will continue while the recovery teams are tracking it down. Have the capsule open up to stop the cooking when the BBQ thermo probe registers the correct internal temperature in the meat. This simplifies things because you just have to plan for enough thermal mass for the correct cooking time, and then design the capsule and orbit to get the thermal mass up to the needed temperature, and since it would heat from the outside in, you could have the cast iron exposed directly to the plasma, and not overheat the turkey.
I once heard that the definition of a good physicist is someone who can calculate anything within a order of magnitude. You are a shining example of this.
Real fun! I didn't know a deorbit could be made slow enough while still generating enough heat, for the turkey to actually cook inside a spacecraft with no heat insulation. I did expect that almost nothing will happen at the beginning and once it get low enough for the air resistance to become significant, the deceleration will quickly go up (as it start to lose altitude and catch more air) with a way to short reentry reaching way too high temperatures for the turkey to cook and not just burn from the outside in, haha
You mixed your units vs scale; your altitude axis says km, but your altitude axis scale is in metres! I.E. When you said 130 km, your scale was 130,000 Very entertaining none-the-less, thank you Scott.
Isolate the turkey in a water bath, use the 15 minutes of reentry heat to heat the water, let the turkey cook in the heated water for several hours after landing. Serve, season with salt and pepper, enjoy!
I just had a very enjoyable 14 minutes in a never-more-than-hypothetical thought experiment that must have taken a whole lot of time to work through. Thanks so much for the effort!
Where else could someone go to get a technical analysis of the effects of deorbiting a turkey. Nowhere. Brilliant! Scott, you're the man! Happy holidays to you and yours!
Geez dude, how much of your life did you devote to this nonsense/genius project? After many years I was just starting to follow the code before it disappeared. Bravo!!! What a great teaching tool for engineering students.
What if you filled the ship with peanut oil, then use that to fry the turkey on the way down? I suggest this because the specific heat of oil is roughly half that of water, and fried turkey cooking times are generally much shorter than baking times. Besides, once you get a Cajun deepfryer, you want to use that sucker on everything.
Very informative video Scott, as always. One addition coming from my view of the materials scientist: in calculating the amount of heat energy needed you would have to not only consider temperature increase and heat capacity, but also all sorts of endothermic reactions encountered when cooking/roasting food, such as protein denaturation, Maillard and also simply evaporation - and these can be quite energy hungry. In case of water one would need about 420 kJ to heat 1 kg from 0 to 100°C but evaporating that 1 kg by boiling would need an additional 2.3 MJ.
Scott, you had too much time on your hands over Christmas - this vid is marvellous! I'm notorious for rocket-launching Haggis on Burns Night (Jan 25th) but then have to take them home to cook. Re-entry might be the answer!
The thought of putting a turkey on a rotating plate, and trying to use that as a reaction wheel all while its cooking, is a very Kerbal idea lol. Had me laughing hard - good video!
Thing is that when you put stuffing inside turkey the bird overcooks while the stuffing is coming up to safe temp. But, what if you surround the turkey in an ablative stuffing heat shield- time it right and both are cooked at landing. Maybe splatchcock the turkey as well for aerodynamic reasons.
That'd be a call for the Butterball Hotline to deal with, surely. Or you could just ask the personal chef to the King of Motor Sales in Fargo, ND - Phil Baharnd.
@@alanholck7995 We always make the stuffing on the side, for that reason. I think with an 80 kilogram 1 meter radius 'MIRV' oven, we can find room for stuffing, potatoes, and pumpkin pie!
This was splendid. @ScottManely this was just incredible, hilarious, and downright educational. And now I'm hungry. *Watches the skies for a Turkey chute*
You can easily cook things longer after it hits the ground by using a heavy capsule that takes a lot of time to cool off. You could find a material that melts around the upper limit of cooking temperature and line the inner wall with packets filled with this material. They will melt to prevent burning the turkey and solidify to maintain that temperature for longer.
This is up there with the guy who figured out how many times you would need to slap a chicken breast to cook it. Answers to questions no one asked but are really glad we found the answer to!
Hilarious! One small correction: I think the altitude values you use are in meters, but the label that is sometimes visible says kilometers. Edit: You even say “130,000 km” near the end of the video. We know what you meant :)
Hi Scott, the over-heating at the end of the re-entry could be solved more simply by having some kind of insulated container within the spacecraft that has doors. The doors are open for the majority of re-entry until the temperature starts to get too high, at which time the doors close and prevent the temperature inside the container from getting any hotter. Imperfect insulation or some kind of vent could be utilised to prevent the temperature inside the container from dropping as the turkey continues to cook.
Question. Would it make sense to take into account the time it takes for recovering the spacecraft as additional cooking time, as the “space oven” slowly cools down on earth ? Are rockets warm on the ouside when they come back ? Happy holidays Scott.
I love it. Thank you Scott. I think I would use the skip technique and enough thermal mass in the oven to prevent scorching and hold it warm during the cold between skips. Something like Townsends 18th century stone oven. Also it can finish cooking after it reaches the ground. Cooks call it resting.
I love how indepth this is. I do agree with other comments about spatchcock cookjng. Even better with metal rods (skewers) through the thicker sections to help heat transferance. My issue is i live all the trimmings too. Adding in methods to cook roast potatoes and to make gravey from the juices might get overly complex.
amazing, 20 years of the food industry...never seen anyone put soooo much effort, whom is WAY smarter than me, into cooking a turkey...well done Scott and all that helped with all the ridiculous math for this...hehe
Your water resevoir for dumping mass could be used as retro thrusters if you vented the steam in the right directions, even enabling the spin you mentioned.
LOL! Thank you for the laughs Scott. This is actually somewhat similar to the problem of people who want to cook something off a rocket launch: too high heat/too short time. But there is one food that could plausibly be cooked during a liftoff, marshmallows. So, since you seem to have time on your hands, try this one: What is the optimum distance from a launch pad to place a marshmallow on a rotating spit so that it is lightly toasted and consumable by the end of heating, say T+00:10

Your mad as and I love it. ❤️ It is funny too see that even extremely smart people such as yourself still trip over metric and call 130,099 km instead of metres. We had (and sometimes stil do) the same units problem when trying to get our heads around metric back in school.
A minor issue, but one that must be mentioned. When you were showing altitudes on the re-entry charts, you mentioned that the distances were in kilometers, but the altitudes were actually given in meters. I began cooking my turkey at 1:20 PM EST, but at 120,000 km. It is now 5:17 PM, my turkey is unfortunately in a high elliptical orbit abound the moon, and I forgot to put the foil on it. Also, it isn't Christmas. Would it be feasible to use the gravitational forces around a black hole to not only travel back to Christmas, but also maybe cook a very frozen, somewhat dusty bird? Please respond with text only, as a phone call will take around 170 years to reach me. I'm on my way to Sag A* and... I forgot to get the turkey. Damn.
Turkey Math is hard... Julia Child is just a gasp. I failed my Turkey Dynamix class. So when do you think they will try this? How big would the recovery zone be? "Aerospace Turkey Roaster" patent pending..
Wild thing is if this had ever come up when Julia Child was in her heyday, she would absolutely have talked about this on her TV show. Remember, she was an OSS employee in WWII.
Scoot, thank you for this. Just in time to start planning on Thanksgiving dinner 2023. I'll start working on my entry vehicle now. I can just see millions of these dropping back to Earth on Thanksgiving day.

I just had a very enjoyable 14 minutes in a never-more-than-hypothetical thought experiment that must have taken a whole lot of time to work through. Thanks so much for the effort!
This has to be the best video currently on TH-cam. Just absolutely love your channel. 👍
When Scott goes into beast-mode calculations... Watch out! 🦃😂
This is a surprisingly well researched video for the topic it is talking about.
This is some of the most quintessential Scott Manley content
Where else could someone go to get a technical analysis of the effects of deorbiting a turkey. Nowhere. Brilliant! Scott, you're the man! Happy holidays to you and yours!
Hi Scott, if you are intending to publish this important piece of work, I suggest changing the altitude axis labels from km to m.
Geez dude, how much of your life did you devote to this nonsense/genius project? After many years I was just starting to follow the code before it disappeared. Bravo!!! What a great teaching tool for engineering students.
What if you filled the ship with peanut oil, then use that to fry the turkey on the way down? I suggest this because the specific heat of oil is roughly half that of water, and fried turkey cooking times are generally much shorter than baking times. Besides, once you get a Cajun deepfryer, you want to use that sucker on everything.
I would fear this might increase the risk if a BLEVE event if the oil got too hot!
@@DrRusty5 that might even be utilized in a kind of self-stabilizing temperature control of the vessel
In this case it's probably better to use sesame oil , slightly higher flash point.
@@DrRusty5 Relief valves are your friend.
Very informative video Scott, as always. One addition coming from my view of the materials scientist: in calculating the amount of heat energy needed you would have to not only consider temperature increase and heat capacity, but also all sorts of endothermic reactions encountered when cooking/roasting food, such as protein denaturation, Maillard and also simply evaporation - and these can be quite energy hungry. In case of water one would need about 420 kJ to heat 1 kg from 0 to 100°C but evaporating that 1 kg by boiling would need an additional 2.3 MJ.
This turkey S T A C K E D
Scott coming in with answers to the real questions. I feel like we need more of this!
🤯 only you Scott would research this 😆 Good job!
Scott, you had too much time on your hands over Christmas - this vid is marvellous! I'm notorious for rocket-launching Haggis on Burns Night (Jan 25th) but then have to take them home to cook. Re-entry might be the answer!
Great presentation.
Do another having a cooking oil filled capsule so as to deep fry.
The thought of putting a turkey on a rotating plate, and trying to use that as a reaction wheel all while its cooking, is a very Kerbal idea lol. Had me laughing hard - good video!
I have one question that could change all of the numbers you have come up with. Is this a stuffed or unstuffed turkey?
Thing is that when you put stuffing inside turkey the bird overcooks while the stuffing is coming up to safe temp.
But, what if you surround the turkey in an ablative stuffing heat shield- time it right and both are cooked at landing. Maybe splatchcock the turkey as well for aerodynamic reasons.
That'd be a call for the Butterball Hotline to deal with, surely. Or you could just ask the personal chef to the King of Motor Sales in Fargo, ND - Phil Baharnd.
Is the stuffing cranberry and pistachio or does it include sausage mince?
@@alanholck7995 We always make the stuffing on the side, for that reason. I think with an 80 kilogram 1 meter radius 'MIRV' oven, we can find room for stuffing, potatoes, and pumpkin pie!
Read this with the same energy as a laden or unladen swallow.
This was splendid. @ScottManely this was just incredible, hilarious, and downright educational. And now I'm hungry. *Watches the skies for a Turkey chute*
You can easily cook things longer after it hits the ground by using a heavy capsule that takes a lot of time to cool off. You could find a material that melts around the upper limit of cooking temperature and line the inner wall with packets filled with this material. They will melt to prevent burning the turkey and solidify to maintain that temperature for longer.
This is the kind of practical science we need more of. Thank you Scott Manley
This was a lot of fun, informative, and spot on for the spirit of the time of year. Thank you for putting a smile on my face!
Definitely one of my All time favs, lotsa laughs! Thanks Scott, and Happy New Year!
Dude you're hilarious! This is awesome. And exactly what the internet was made for! 🤣
Missed opportunity, should have ended this one with "I'm Scott Manley. Fry safe."
Perfect, now I'm hungry... Again! 😂
Thanks, Scott!!!
Stay safe there with your family! 🖖😊
And happy holidays!
This is up there with the guy who figured out how many times you would need to slap a chicken breast to cook it. Answers to questions no one asked but are really glad we found the answer to!
Hilarious! One small correction: I think the altitude values you use are in meters, but the label that is sometimes visible says kilometers.
Edit: You even say “130,000 km” near the end of the video. We know what you meant :)
Great fun! But 130000km is beyond the geostationary orbit, isn't it?
@@victoradam8485 Exactly. I think he meant to use km figures in the graphs but used meters in the calculations.
@@germansnowman I think so too, but Mr Biermann, my grade 10 physics teacher would have subtracted points from his grade for mixing up his units😂
Wait... did Scott just turn a Vostok 1 into a turkey oven? I love this guy.
This was great, funny and informative 😂
Hi Scott, the over-heating at the end of the re-entry could be solved more simply by having some kind of insulated container within the spacecraft that has doors. The doors are open for the majority of re-entry until the temperature starts to get too high, at which time the doors close and prevent the temperature inside the container from getting any hotter. Imperfect insulation or some kind of vent could be utilised to prevent the temperature inside the container from dropping as the turkey continues to cook.
You sir, are certifiably AMAZING! Thanks for giving us all something to appreciate amid bellows of laughter!
I love science, and this made me smile. Thanks Scott, and happy new year.
Looks like Scott is trying to get a chance to win the ig-nobel prize. Have you submitted this thesis to a scientific publication yet ?
Perhaps the Journal of Irreproducible Results?
This right here, videos like this, is why I love this channel so much 😂
Question. Would it make sense to take into account the time it takes for recovering the spacecraft as additional cooking time, as the “space oven” slowly cools down on earth ? Are rockets warm on the ouside when they come back ? Happy holidays Scott.
you just calculate the deorbit to land on your doorstep... we do it with ICBMs
@@adfaklsdjf SpaceX reckon they can land a Starship back on the launch tower, so landing your turkey in the back yard doesn't seem unreasonable.
I love it.
Thank you Scott.
I think I would use the skip technique and enough thermal mass in the oven to prevent scorching and hold it warm during the cold between skips.
Something like Townsends 18th century stone oven.
Also it can finish cooking after it reaches the ground. Cooks call it resting.
“As God is my witness, I thought turkeys could fly!”
Now that was good TV 😂
I love how indepth this is.
I do agree with other comments about spatchcock cookjng. Even better with metal rods (skewers) through the thicker sections to help heat transferance.
My issue is i live all the trimmings too. Adding in methods to cook roast potatoes and to make gravey from the juices might get overly complex.
so what you're saying is that cooking a perfect turkey really is rocket science!
amazing, 20 years of the food industry...never seen anyone put soooo much effort, whom is WAY smarter than me, into cooking a turkey...well done Scott and all that helped with all the ridiculous math for this...hehe
Your water resevoir for dumping mass could be used as retro thrusters if you vented the steam in the right directions, even enabling the spin you mentioned.
LOL! Thank you for the laughs Scott. This is actually somewhat similar to the problem of people who want to cook something off a rocket launch: too high heat/too short time. But there is one food that could plausibly be cooked during a liftoff, marshmallows. So, since you seem to have time on your hands, try this one: What is the optimum distance from a launch pad to place a marshmallow on a rotating spit so that it is lightly toasted and consumable by the end of heating, say T+00:10
more videos on nuclear rockets please. would love to hear a little more in-depth about the lightbulb, for example.
also, nertea's ksp mods has some great inspiration for interesting videos (like that nuclear saltwater rocket video of yours).
Or nuclear cooking! Why the hell not? 😬
I admire the dedication you have for this. You turned a ridiculous question into a science lesson. Bravo! 👍👍👍
Great Show and brilliant approach Scott! Obviously a Must have for Science lessons prior to christmas for generations to come. But shouldn‘t it have been „Cook Safe“ this Time? ;) Thanks for your content and all the best for ‘23!
Your mad as and I love it. ❤️ It is funny too see that even extremely smart people such as yourself still trip over metric and call 130,099 km instead of metres. We had (and sometimes stil do) the same units problem when trying to get our heads around metric back in school.
A minor issue, but one that must be mentioned. When you were showing altitudes on the re-entry charts, you mentioned that the distances were in kilometers, but the altitudes were actually given in meters. I began cooking my turkey at 1:20 PM EST, but at 120,000 km. It is now 5:17 PM, my turkey is unfortunately in a high elliptical orbit abound the moon, and I forgot to put the foil on it. Also, it isn't Christmas. Would it be feasible to use the gravitational forces around a black hole to not only travel back to Christmas, but also maybe cook a very frozen, somewhat dusty bird? Please respond with text only, as a phone call will take around 170 years to reach me. I'm on my way to Sag A* and... I forgot to get the turkey. Damn.
I've been waiting for this video so long..
Unfortunately I can only give this a single single like. I love this! Thanks Scott for bringing space science to our dinner table.
This reminds me of an old STYX song...
I've got too much time on my hands ;-)
Happy New Year Mr Manley, and safe flight in 23!!!
This is the "cooking a turkey in// *with* space orbit" content I am here for!
Thank you for this, i have had many sleepless nights contemplating this very puzzle, looking forward to a good nights sleep going forward.
Turkey Math is hard... Julia Child is just a gasp. I failed my Turkey Dynamix class. So when do you think they will try this? How big would the recovery zone be? "Aerospace Turkey Roaster" patent pending..
Wild thing is if this had ever come up when Julia Child was in her heyday, she would absolutely have talked about this on her TV show. Remember, she was an OSS employee in WWII.
Oustanding video! I especially liked the way you came in for the landing (pun intended) involving brine. PURE genius. 😄
Just a basic question! Do we have to do a 48hr defrost before launch 😂 ✌😇
Think a paper is in order, this is proper science, Nobel worthy.
This turkey got me sweating 🥵
Scoot, thank you for this. Just in time to start planning on Thanksgiving dinner 2023. I'll start working on my entry vehicle now. I can just see millions of these dropping back to Earth on Thanksgiving day.
What a good laugh! Thank you sir
04:27 "and so I decided to attack this problem with the power of science!"
I love this Guy.
So I'm watching this 17 hours after it dropped. I'm guessing someone has already applied for a patent?
The chemical energy to put a turkey into orbit could be used to roast thousands of turkeys.
I love the video! Scott at his best!!
