Adam revealed that originally, in the cereal vs cardboard myth, they were going to feed 3 groups of 3 mice; a control with regular mouse food, cereal and cardboard. However, after about a week or so, there was a problem: in the cage with the mice eating cardboard, 2 of the mice were cannibalised by one of them, leaving behind 1 really fat mouse and 2 cleanly eaten mice skeletons. Adam had an original rough cut of the episode with the killer cannibal mouse, which Discovery ordered him to destroy after he decided to show it at a college lecture. Also, iirc, the mouse was eventually fed to Jamie's pet snake.
One of those episodes where you´re thinking± you need to add more copper mass to retain enough energy to flash the water. But you can´t speak to them, 20 years ago.
Yes, a bit of a poor understanding of the concept of thermal mass vs the amount of water that they tried to turn to steam. The amount of stored energy was simply not enough in their designs.
honestly though, from a show perspective that's not great stuff. but for teaching kids a lesson about how far is too far I that scene could have had a good impact
Seeing Adam and Jamie live in Melbourne in 2015 was the best event I’ve ever been to. Especially when they brought out the exploded water heater out on stage and the multi barrel paintball cannon for the finale, that they used on some poor sod in full medieval plate armour 🤣 Adam’s comment about how the aftermath looked like a clown threw up just broke me 😂
19:35 A 24 lbs cannonball is a big one. Usually field guns at the time were 12 lbs or 6 lbs. 24 lbs was usually the largest standard cannonball with anything bigger being custom made. Though for that cannon to work you need a spring valve of some sort to halt the pressure for a second to let it build up.
Yeah, Adam explained this in one of his videos. Some stranger entered the premises and started a brawl. Can't recall what exactly happened, but there was a fight indeed.
Dark teeth doesn't mean they are dirty or worse, just they have been dyed, mostly by coffee, tea or food colorants. Adam's teeth are full of restoration and tartar thou.
First of all, teeth are made of ivory. And ivory is by nature not solid white bit brownish-white or yellowish-white. This is the matter with all teeth wearing creatures on this planet.
@@jpsholland sounds like someones coping about having nasty brown teeth. pro tip, they're meant to be white. Human teeth do not contain ivory either. So you're just talking complete nonsense to cope with your brown teeth.
Re-binging my favourite childhood series. Wonder what would happen if they placed cooking oil in the copper tank, heat it up till flashing point, and drop the water in to cause a grease fire fireball to power the cannon?
it changes nothing, its just sealed preasure you want, 60 psi stays 60 no mather how or what you use, they showd 1/10 of what this cannon and ensurance could do,amaizing
They revisited that myth later. The problem is Leidenfrost effect. Even if you put water into oil, it doesn't flash all immediately. The only way I could think of, is creating supercritical water, and that stuff is WAAAAAY to dangerous 😊
I remember this episode, when it first aired and after what Jamie said after watching the aftermath of Adam using the lathe I was worried that this could be the final season
I don't think Adam could destroy steel lathe with wooden bar. If anything wood just split or shatter into pieces. Although camera seems to show some damage, I am not sure it was from Adam's work. It seems to me Jamie was more pissed off that Adam made a mess and didn't clean it up. Wonder if they resolved that later, or just let it hang.
@@d4slaimlessThe thing about a lathe is that you can fuck it up pretty bad just by using it wrong' even if its empty. Still, I think Jamie was more upset about the mess, which was fair.
@@bird.9346 Yeah its super weird that people try and push this narrative. All they said is that they were never friends. Which you can see why just based on their polar opposite personalities. For a stern and fairly introverted person like Jamie, it is tiring to deal with a reckless ball of energy like Adam. I feel like people who say they hated each other have never worked a real job and experienced a relationship called an "acquaintance". You can work with someone for years and never become friends. That doesn't mean you hate them... It doesn't even mean you dislike them. Some people just don't gel with each other enough to become friends. They can still work together and accomplish goals though. It's very bizarre that people seem to think there's only two options. You're either friends with someone or you hate them 😂
My thought: That copper cannon didn't have enough thermal mass to "flash" the water to steam. The barrel cools too quickly. Having a solid, heavy metal block at the base of the barrel might do it. The copper nails they later used are the same thing. Same on the larger version. A thicker, heavier barrel heated up might work.
A pressure vessel should be hydraulically tested at twice the rated pressure. This helps locating leaks at the same time it ensures it is safe with gas (steam). A boiler should have a safety valve. A calibrated rupture disc could act as a safety valve and at the same time be the firing mechanism.
The DIY calorimeter relies on the assumption that combustion extracts the same amount of energy as digestion. Given that cardboard is primarily composed of cellulose, which is a carbohydrate that humans don't have the enzymes to break down, much of the energy from combusting the cardboard would be unavailable to us via digestion.
exactly, a calorimeter is just to get a rough estimation. what is a problem when not all calorical values companies put on labels are the real extractable calories.
Did anybody else notice Jamie's epic Arachnophobia jacket, from his time on set, building the big robot spider for that movie it was one of his first special effects jobs actually
Maybe this is old news, but if the sock at the end of the barrel fills with air I have a feeling you have not got anything that resembles a seal by the cannonball? Maybe you could add a rim to the pipe, put a heatproof seal then put in a circular disk, then the cannonball, and maybe before the cannonball you have some kind of wad that is also heat resistant so hopefully the ball is pushed out straight. Or something like that.
Pretty sure, in all of those designs, they lost all of the steam pressure just from the steam cooling on that ridiculously long barrel. A shorter barrel would probably have had way more power but way less accuracy, which would have fit the myth better imo.
In my childhood I had that old book telling short stories about different technical inventions, incidents, accidents, technologies but it was rather about XIXth century. And my most favorite story was about a steam engine which's boiler had go out of control and exploded with terrible shambles.
I think that Archimedes COULD have...it's the valve that's the issue, no? Heating the water in a chamber beforehand was the big difference-maker. We know the romans knew how to use valves and control water (aqueducts and boilers recovered from Pompeii)- and many of their technical achievements came after sacking Greece. I can certainly think that it's doable, if not quite at the levels shown here at 60 PSI/one mile. I'd estimate 500 feet is still a feat for antiquity that would make people sit up and take notice, considering the trebuchet wasn't around at that time, and the catapult had similar range. Would have been filed under 'interesting enough to make a note of, but we have catapults, so why would we bother scaling it up?'
The process of evaporating water requires a lot of energy. Studies show that 30 liters of atomised water should theoretically be enough to extinguish a relatively big kitchen fire.
My alteration plans for the cannon: a smaller, weaker sealed pressure vessel of water inside the larger, stronger one. Just keep heating until the sealed one bursts, a la water heater.
@@bertjesklotepinoyeah 1 gram of cereal being 9 calories would mean that it has to be pure fat or some fuel, there are only 4 calories in a gram of carbohydrates and proteins, and the cereal definitely had a lot of sugar so it can't be pure fat 😂
"All high explosives is, is a material that changes from solid to gas very rapidly" is also nonsense. Explosives are based on chemical reactions, not on sublimation. Oh, and there are liquid explosives too.
@@thomasr2472 this was a kids show. explosions are rapid expansions, not chemical reactions. and an explosive is a material that can rapidly expand. nothing says it has to be based on chemical reactions. to bring that back to more understandable language that kids can relate to is not a bad idea.
I reckon it must be a heat capacity issue. The gun is cooled by the water as it enters, and so it can’t turn it to steam quickly enough no matter how hot. You need something that can accumulate a lot of heat inside the barrel and release it without cooling too much
Unfortunately the design seemed to interested in making a steam cannon, not a steam rocket shell. Create a heavy bronze bottle with a pressure cap and a long straw from the cap to 75% into the bottle. Fill the bottle 50% full of water and hammer on a plug for a cap (designed to file before the bottle) sit a pipe in a bath of boiling oil and drop the pre heated bottle in like a mortar shell cap facing down. It would go a very long way if fin or spin stabilized.
Mythbusters was always a very American TV show, but few things sum it up as well as people going "Hey, are Adam's teeth as terrible as they look at a glance?" and the team/producers interpret that as "How white are everyone's teeth?" instead of "How much plaque/tartar is in there?"
It's much to late now, but what if in regards to the steam cannon, what if the heat expands the metal just a bit to much the ball and barrel no longer seal? Therefore no thrust can be applied as most of the air escapes....
For the death ray - what could have happened if the Mythbusters took out the human factor in mirror control and instead used GPS controlled servo mechanisms to focus the mirrors at "ONE SPECIFIC" spot in relative position to the sun?
Powering the steam canon using the water heater 'rocket' from November 2007 might be much more straightforward. That was rated at 160psi. It blew at about 350psi, so 200psi might be "safe". It's 52 gallons of water flashed to over 52,000 gallons of steam. The valve and pipework would still be problematic, but feasible. A water-heater cannon at 160psi might be reusable. Best Wishes. ☮
i built a steamcannon with the pathfinders.... just a simple metaltube closed on one end, water in, closing up with potato , tinto the firepit with it and wait till the boooom. This works. I dont know why they are doing this complicated "stuff" here...
Yeah, that was a bad take from Adam. He should've fessed up and at least cleaned up. Adam of today would have reacted the exact same if this was done by his kids or a friend in the shop. But he does admit now that he was not always very nice to work with (and i can understand that Jamie also wasn't always the easiest to work with).
@@Games_and_Music yeah, I think Adam got older and matured more. Also, yeah, same with Jamie, both are very strong willed people. Just comes down to we arent perfect and all have our flaws.
with the way they tried to pin that damage on adam. I am like 99% that the whole thing was scripted. that damage does not look new enough and any licensed professional would be under investigating if they messed up that bad with a piece of wood on a machine that is rated for steel. adam might be chaotic, but you don't get the work he got by being unprofessional
i wish they could show the original cut of this episode with the cannibal mice youtube has age restrictions and things could be blurred so it would be an interesting comparison from first draft to this
Oh yeah I forgot that mice test in cereal myth that part wasn't cutted it was unaired. Long story short Adam told in interview about it, they used mices to test it but the cardboard one ended with one fat happy mouse. Inteview name is (Cannibal Mouse: The MythBusters Episode You'll Never See)
@@maltesefalcon85 And none of those cuts weren't in any episodes of Mythbusters. Remember your said "original cut of this episode" Adam might have that footage, however it was never included in this Mythbuster episode.
"1 gram of cereal equals 9 calories"? That can't be right. 9 kcal per gram is about the same as pure fat, which has significantly more calories than sugar or protein (or even alcohol). Froot Loops should be about 4 kcal per gram according to the nutrional information on the box.
The show has been over for a decade loser. Adam and Jamie didnt get along, it is a known fact. They both said so on the record. Grant isnt even alive anymore. WHAT THE HELL ARE YPU TALKING ABOUT? DO YOU REALIZE THIS SHOW WAS ON TV 15 YEARS AGO?
It's on a few Mythbusters videos. The top left section is where BBC logo would be if it was shown on BBC but I don't recall it ever being on the BBC. Would like to know also
31:00 I think Mom was speaking metaphorically. If ya ate four times the box at a fraction of the cost of the "food" (whatta joke), ya might get somewhere. We got's ta stop eating GARBAGE, man!
that first mini steam cannon.... why did they heat it with propane torches and yellow flames? Why did they not use an induction heater, or just an electric heater of some sort?
Well, they did find out that it is indeed not a bad idea to preheat the water in a sealed container or canister. Right? At the end they basically took a barrel to act as a container to preheat the water to steam..... basically making a bomb. I have no clue what you mean by those explosive popcorn makers. Am not making popcorn that regularly myself to buy one of those. But my guess is that there might be better ideas to actually get a steam cannon to work. Steam after all has a lot of power. @@calumhughes2778
the first one was to try out a more authentic version to get some baselines. it's the simplest way to do it and it uses tools and techniques they would have used at the time.
The amount of energy required to flash the water into explosive steam/plasma is extremely high. You would need to create the pressure in multiple chambers in series.
This cereal myth is one of the few where I really dislike their approach. It's so unscientific and besides the point. 1) The whole point of the statement is that cereal has so little value in terms of stuff you need (vitamins, minerals, etc.) that the box would be better. I doubt anyone accused the sugar covered cereal to have too few calories... 2) Their calorimeter is easily proven as completely wrong. 1 gram of pure fat contains 9 calories, and that's the maximum anything has. They could've known that so easily. Of course cereal would be way below that. 3) Even ignoring all the heat lost to the environment etc., burning food for calorie estimates is so imprecise it's just not worth it, as it's not like everything that burns is digestible. Cardboard, for example, contains a lot of indigestible but flammable fibers, it tells us nothing. They test a lot of dumb myths, but they're almost always rigorous in their methodology. Here they misunderstood the myth and also did a horrible job testing that misunderstanding. A miss on all points, which is so surprising and rare from them.
Lol, ask an american what the best for your health is, and they choose the sugar filled cereal because it has more calorie lol. Ok for all of you who do not want to get diabetes... Yes sugar filled cereal has more calorie, more fat, more vitamine, more protein then the cardboard box. But the ratio of sugar to the other nutriments is so high, that with a single bowl you get 1/3 of teh calorie you need in your day but barely enough of everything else. At least the card board box, got a less calories and most of those calorie are inside fibre, meaning they are slow burning calorie, compare to the high sugary cereal quick calorie. So yes cardboard box is still more nutritious then the cereal, but for your health sake go eat an apple instead.
A calorimeter is not an accurate measure of what can be digested by humans. To a first approximation, people can only digest right-handed molecules. Calorimeters are chirality agnostic.
That's not true at all, where did you hear that humans can only absorb right handed molecules? For one all the amino acids Earth life needs are left handed, humans wouldn't survive if we could only process right handed molecules.
Oh, I would be extra-grumpy if someone used my equipment, nearly destroys it and then leaves it all covered in sawdust! Jamie, I feel your anger.

12:31 Mission accomplished, proof of concept, unleash the big guns!
26:18 3...2...1..
Didn’t seem like the big cannon have the seal around the projectile like the little one did
Anyone else noticed how those temperature laser guns only measure the very outside temperature just the surface exposed to the air?
i built a steamcannon with the pathfinders.... just a simple metaltube closed on one end, water in, closing up with potato , tinto the firepit with it and wait till the boooom. This works. I dont know why they are doing this complicated "stuff" here...
The older I get, the more I understand Jamie's pov regarding Adam.....
Yeah, that was a bad take from Adam. He should've fessed up and at least cleaned up.
Adam of today would have reacted the exact same if this was done by his kids or a friend in the shop.
But he does admit now that he was not always very nice to work with (and i can understand that Jamie also wasn't always the easiest to work with).
@@Games_and_Music yeah, I think Adam got older and matured more. Also, yeah, same with Jamie, both are very strong willed people. Just comes down to we arent perfect and all have our flaws.
Adam gives strong ADHD vibes
Yes he does@@patrikboij7560
with the way they tried to pin that damage on adam. I am like 99% that the whole thing was scripted. that damage does not look new enough and any licensed professional would be under investigating if they messed up that bad with a piece of wood on a machine that is rated for steel.
adam might be chaotic, but you don't get the work he got by being unprofessional
34:01 Not often you hear Jamie laughing like that.
"A small Texan man punched it out of my face years ago" 41:02
i wish they could show the original cut of this episode with the cannibal mice youtube has age restrictions and things could be blurred so it would be an interesting comparison from first draft to this
Oh yeah I forgot that mice test in cereal myth that part wasn't cutted it was unaired.
Long story short Adam told in interview about it, they used mices to test it but the cardboard one ended with one fat happy mouse.
Inteview name is (Cannibal Mouse: The MythBusters Episode You'll Never See)
@@Mikael404 theres still some footage left in the episode but none of the stuff left adam mentioned he had a rough cut he showed at colleges
@@maltesefalcon85 And none of those cuts weren't in any episodes of Mythbusters.
Remember your said "original cut of this episode" Adam might have that footage, however it was never included in this Mythbuster episode.
@@Mikael404 28:17 in this very youtube video its in black and white but its there
@@maltesefalcon85 So where is that fat mouse in this part and are they mentioning result of that test in this video?
I would've laughed my ass off if they had gone to 170psi and sunk a tourist boat in the bay. 😂
"1 gram of cereal equals 9 calories"? That can't be right. 9 kcal per gram is about the same as pure fat, which has significantly more calories than sugar or protein (or even alcohol). Froot Loops should be about 4 kcal per gram according to the nutrional information on the box.
Comment section is super weird. People really want the Mythbusters to hate eachother.
The show has been over for a decade loser. Adam and Jamie didnt get along, it is a known fact. They both said so on the record. Grant isnt even alive anymore. WHAT THE HELL ARE YPU TALKING ABOUT? DO YOU REALIZE THIS SHOW WAS ON TV 15 YEARS AGO?
... I reckon the ancient greeks could if they used a burst disk behind the projectile.
Did it go from Archimedes steam cannon to Da Vinci's steam cannon, or did I imagine that?
this was such, is such a good show
Bigger relative Vapourchamber with a higher thermal mass would’ve done the trick probs
They should have superheated the water before they injected it into the hot part of the barrel.
The steam cannon was mental , hahaaha 200 PSI would have sent that off the runway
The problem is the Leidenfrost effect. The hotter the pipe the less water evaporates.

38:19 💀
Surely they could have removed the ink part of the cardboard I know from Rolling joints and you making roches you can peel the layer of ink off
steam cannon was never going to work with copper and solder, the solder would be too soft
in the business we call this foreshadowing.
The moment they realized how bad of an idea 200 Psi was 😳
what about the use of greek fire?????
RIP Grant
Just wondering why the BBC and MasterChef UK are being advertised on a US science show...
It's on a few Mythbusters videos. The top left section is where BBC logo would be if it was shown on BBC but I don't recall it ever being on the BBC. Would like to know also
Same reason a lot of UK shows have a US company like Netflix's logo slapped on it. Because they bought the rights, I would assume.
Those "eating" contests are the stupidest thing ever conceived. Plus it's gross.
In 2024 a 12 year old was reported to succeed in the death ray.
21:50 Someone's a little camera shy.
"Solid water"?
🤔
Dine on box... 😂
Bogladite (MIB) speech that's how it was done
31:00 I think Mom was speaking metaphorically. If ya ate four times the box at a fraction of the cost of the "food" (whatta joke), ya might get somewhere. We got's ta stop eating GARBAGE, man!
Wasn't the point of Archimedes Sun Ray weapon to burn the sails of the ship causing a fire ?
man, i wish jamie had his program...
steam is no joke
SHOW DEMAIS
45:55 Lol.
People who have red hair (naturally) have yellower teeth, it's an unfortunate genetic trait
Was there a fight in the background at 21:50???
Your camera sometimes makes you look like a carrot😂😂😂
Why suddenly move the myth from nutrition to energy that isn't science you just tested a different myth than the one your mother claimed.
that first mini steam cannon.... why did they heat it with propane torches and yellow flames?
Why did they not use an induction heater, or just an electric heater of some sort?
Or preheat water in a sealed canister like those explosive popcorn makers. I assumed they would have done that way with the build
Well, they did find out that it is indeed not a bad idea to preheat the water in a sealed container or canister. Right?
At the end they basically took a barrel to act as a container to preheat the water to steam..... basically making a bomb.
I have no clue what you mean by those explosive popcorn makers. Am not making popcorn that regularly myself to buy one of those.
But my guess is that there might be better ideas to actually get a steam cannon to work.
Steam after all has a lot of power.
@@calumhughes2778
the first one was to try out a more authentic version to get some baselines. it's the simplest way to do it and it uses tools and techniques they would have used at the time.
calorimeter? huh? does coal have a lot of calories if it just burns? 😀
The amount of energy required to flash the water into explosive steam/plasma is extremely high. You would need to create the pressure in multiple chambers in series.
This cereal myth is one of the few where I really dislike their approach. It's so unscientific and besides the point.
1) The whole point of the statement is that cereal has so little value in terms of stuff you need (vitamins, minerals, etc.) that the box would be better. I doubt anyone accused the sugar covered cereal to have too few calories...
2) Their calorimeter is easily proven as completely wrong. 1 gram of pure fat contains 9 calories, and that's the maximum anything has. They could've known that so easily. Of course cereal would be way below that.
3) Even ignoring all the heat lost to the environment etc., burning food for calorie estimates is so imprecise it's just not worth it, as it's not like everything that burns is digestible. Cardboard, for example, contains a lot of indigestible but flammable fibers, it tells us nothing.
They test a lot of dumb myths, but they're almost always rigorous in their methodology. Here they misunderstood the myth and also did a horrible job testing that misunderstanding. A miss on all points, which is so surprising and rare from them.
Lol, ask an american what the best for your health is, and they choose the sugar filled cereal because it has more calorie lol.
Ok for all of you who do not want to get diabetes...
Yes sugar filled cereal has more calorie, more fat, more vitamine, more protein then the cardboard box.
But the ratio of sugar to the other nutriments is so high, that with a single bowl you get 1/3 of teh calorie you need in your day but barely enough of everything else.
At least the card board box, got a less calories and most of those calorie are inside fibre, meaning they are slow burning calorie, compare to the high sugary cereal quick calorie.
So yes cardboard box is still more nutritious then the cereal, but for your health sake go eat an apple instead.
A calorimeter is not an accurate measure of what can be digested by humans.
To a first approximation, people can only digest right-handed molecules.
Calorimeters are chirality agnostic.
That's not true at all, where did you hear that humans can only absorb right handed molecules? For one all the amino acids Earth life needs are left handed, humans wouldn't survive if we could only process right handed molecules.

‘Failure is always an option’
im currious , because i saw footage of the original experiment and several recreations and all worked, i don't get it why it failed.
