11:41 Peter salty he lost to Sam's Championship Rocket. Like a hypersonic jet, Sam's rocket used low stability to its advantage. It performed a 180 degree maneuver after crushing the height challenge to race back down to Earth in record time. Peter would do well to better understand the engineering genius of Sam's creation.
lol
Absolutely.
I was thinking Sam's rocket was epic too.
If you've lost, be gracious and stop seeking to define the rules AFTER the contest. Sam's rocket could be adjusted to fit Peter's definition and STILL WIN.
Sam's rocket was spin stabilized by it's somewhat cooked fins. Once at altitude it tumbled allowing for a soft non damaging landing. It is genius. Or dumb luck.
Spoilers
Whoo! Sam killed it! :)
demonitzed on the first frame, go big or go home i guess
I was pretty surprised, pretty happy, and then not surprised when I remembered they're in Ohio. Hello from Indiana.
EthanKRETA knowing yt they would have if they could
EthanKRETA idiotic liberals....
There is an advert at the end of the video
Esad Zec Friend you sound like a country hick
Peter is like a little child, doesn't know how to lose. Don't hurt Sam!:(
too true . just about to comment that hahaha
@@maxreeves9076 He seems to be spoiled too, never had to go without anything in his life including experiencing humiliation. Slams things around as if to say, no worries if i break something i'll just buy more, I may un-sub to be honest.
Nailed it. That was painful to watch. I know who I'd rather be friends with. Sam rocks.
Calm down you incels
Children r better than adults
Love the channel but hate it when Sam comes up with a good idea and peter doesn’t know what to do and gets jealous and throws it in the bin...
He is right though, it changed the propulsion type from a rocket engine to a cannon/projectile. I could see an asshole teacher giving it a D or F for that reason.
The challenge was an Alka Seltzer Rocket, and he still gave it 1st place.
Seems he treats his friend like crap, he could had used Sam's launcher, just leave the valve open. Peter you need to be nicer, open jealously does not go over well.
Papadoc Fpvp
A rocket provides it's own propulsion. Using Sam's cannon is cheating, because it's the cannon gives propulsion to the object, which means the object is not a rocket anymore, it's a projectile.
@@roelvian neither one carried the propulsion unit on the rocket, just delivered pressure differently, one popped when the pressure was to great, the other had a valve, and a smaller pipe to increase pressure. They were done in different ways, and I do understand what your saying, but Peters did not carry the propulsion fuel either.
Papadoc Fpvp ok then, listen to me.
Rocket -> self-propelled
Projectile -> gets propelled
Peter's rocket -> self-propelled by the reaction inside the rocket. The energy was released FROM the rocket.
Sam's Cannon -> Propelled from the reaction inside the pressure chamber. The energy was released from the chamber ONTO the projectile, which pushed it forwards.

i just watched franks 100 best life hacks video and now this.... how weird
now we gotta balance glasses of chocolate milk on our heads and sing the bikini bottom anthem
4:24 got eem
jury's still out on that one, it was practically at waist level exactly.
does the tie go to the runner? find out next time on GOTEEEEMMM
If you really wanted to go nuts with alka-seltzer rockets, you could try for a "hybrid" design, with a hollow cylinder core of mixed baking soda and citric acid ("fuel"), then pumping water in from the top ("oxidizer"). Getting the exhaust nozzle design and flow rates figured out would be tricky, but it might work pretty well with some trial-and-error. Bonus points if you pre-heat the water to speed up the reaction and increase the internal pressure.
Instead of water use hydrogen peroxide with a platinum catalyst to heat liquid before it gets to the core. 😂 Over complicated is my middle name
I also love spraying hot hydrogen peroxide everywhere on a cold winter morning.
@@userPrehistoricman yeah I heard that is how Jake Paul does the blonde tips in his hair
@@userPrehistoricman what should I expect you I've never tried this?
Just by coincidence Cody's lab did vinegar and baking soda Rockets the same week. His did in fact store his fuels separately and use electrically powered pumps. It didn't work that easily but it was a great demonstration particularly for teaching.
Why is Peter so hard on Sam? The world may never know
uuhhhhhh are you gonna murder him or something because you said "*The world will never know*"
Because Sam is a secret genius and Peter is jealous. I mean did you even look at his rocket at 8:55?
@@tengkuadam1399 ikr just cos we think he's great doesn't mean he can't be a bit of a twat
he mean to almost everyone..
I would love to see a perfected model of Sams design!
Dave Knop on the video!!!! thanks for sharing Peter and great to include Dave! cheers!

Nice job Sam!!
Did you try holes on the launch tube? Like a paint ball gun, it could help pull air off the canister as it travels up the tube.
Your also going to loose propulsion.
@@RCOverKill but isn't all the propulsion in the canister?
I have a vision of Peter (or his father) riding atop one of these. Stay tuned!
Lol
“It hits the corner”
But Peter.... it’s a cylinder
drill a little hole into the cap (like 3mm), assemble it with a piece of foil between the body and the cap, maybe the pressure would rupture the foil and you´d have a little nozzle? (otherwise build a launcher with a litle needle and a guiding rail where you can drop the rocket onto the needle) also crush the seltzer for faster and more complete dissolving, baking soda and vinegar work very well as propellant because of that surface area
In real life this is an upside down form ballistic shooting. If you added the weight of that bottom cap and you kept the fuel on board for the bulk of the flight and therefore had to work with the rocket equation You lose out. But I'll try it this weekend with my son. Personally I think that What I am going to call "combustion control" is the next big key. Pre grind the Alka-Seltzer or and then control the point where the cap is going to release for Max pressure.

-Peterstripol 2019
When I was 12 or so I put Alka seltzer in an mostly-empty toothpaste tube, added water and closed it... in the upstairs bathroom of my parents new house. It dawned on me that this might be a problem. I ran to the stairs, down two flights, opened the front door and threw it as hard as I could. It burst in mid-air. Possibly one of my finest moments.
You started with a gun, INSTANT DEMONITISATION!
Love your vids, Peter.
Man, love your vids. Don’t stop making your amazing content!
I would go eat arbys with Sam, he seems like a cool guy👍
Peter, you honestly almost always criticise Sam's builds. Each time he shows up you immediately say it's basically trash and nobody wants it. I know it's in a fun way and so, but if you hear those things every single time, eventually it's just annoying.
Felt like maybe you should think twice about it!
sam usually spends no time and little efford into his build trying to cheese through the challenge while peter often spends days, so he makes fun of the janky joke try to elevate the bigger part of the video in good sport
@@TheJaniii123 Sorry, what part of "I made this badass copper pressure gun" looks like it took no effort?
Stop being offended on behalf of others.
that's Peter
4:06 just drill holes into the side for every canister length, wouldn’t that equalize the pressure?
Cool idea. I'd like to see you come up with a version that incorporates a nozzle to focus the thrust
Only a handful of people on earth could keep me interested in a video that's mostly about the stoichiometry of alka-seltzer, that's something special right there Peter
Peter I have watched you for 2 years now and i dont see how you still have under 1 million subscribers, I even told all my friends about you! You inspire me!
I was here so early the video was still processing. So first? But "first" comments are stupid so instead, Awesome video I haven't watched yet keep up the great work! X-D
EDIT: Sam didn't really cheat so.....
Really.
Oh and first😂😂😂
I guess you are jealous

The legend is back
I love how this show is usually Peter overengineering something and incorporating modern technology into an older concept and then Sam shows up with something he thinks he is gonna have fun with, but lest we all forget
Sam would take that ring to Mordor uncorrupted with Peter on his back
Make a De Laval nozzle and use it in an air-powered rpg nerf thing. Basically, take one of those nerf foam footballs, put an air canister and the nozzle inside with an rc valve. Flick a switch, the valve opens, and you have launch. The foam will protect it on landing (hopefully) and the nozzle should be 3D printable, so you won't have to use metal (though you could if you want.)
Awesome thing it's a cool diy experiment!
Keep more new content coming, please. Thanks Peter & Sam
I love the BACKGROUND of your toll garage
Where on earth does one source film canisters in this TYOOL 2019?
Do you not have phones? Amazon has a 60 pack for $17.80, and it's prime.
A lot of people keep them on hand for storing small things. Or portions of cannabis
They still sell 35mm film in them as well.
@@RCOverKill great as an emergency shot glass as well...cheers.

my science teacher scared everyone by setting a couple of these off in class last week saying it was "erosion". And now you make this video.
Haha great video, I really enjoy seeing Peter and Sam's competitions. Keep up the good stuff!
I have a challenge for you, make a model rocket, any size, any shape, any thrust method, and see the highest you can possibly go.
Hello from France !
This video give me Mythbusters vibes, thanks you for making great and educative content on youtube !
Keep up the good work! Love your videos :) Cool to see Dave in your shop, tell him to make more videos they are great :)
I love the work you do
Great as always
Cool creative thinking exercise!
😂 kids are wondering what a film canister actually is.
No, we’re really not 🤣
Nope
It’s pretty self explanatory
Ok boomer
excellent as always
Thanks for the good childhood memories
I think he should post more!
Peter was like, it doesn’t go high enough, so here’s a brushless motor...
Omg I never thought I'd see the day, when sam pulled out that launcher! Hahaha thing is I probably would've done something like Peter and too!
Sam for the win!!! Maximize the gas pressure with the available fuel... in other words, the CO2 gas is the propellant and ideally you would want as high a gas to water ratio as possible. Sams idea kept the gas expansion contained outside of the rocket so it was probably lighter during flight. So, a re-design that may be within Peter's definition of a "rocket" may be using two film canisters: one to act as a reaction chamber that is sealed shut after the fuel is mixed, a small tube allowing the gas to travel into the dry rocket chamber with the standard pop-off lid.
Sam’s is actually really cool
We used to make those as kids with baking soda and vinegar, with a piece of sponge to hold the baking soda at the top until you flip it over and mix them. You had about 3 seconds to throw it before it blew up and filled your eyes with acetic acid. Good times!
I think you should challenge Destin and his kids from Smarter Every Day. Dudes a rocket engineer lol
Try taping the lid to the on the body of the small rocket to get higher pressure
You got an Osmo
I always wanted to get one but I’m not sure if I should get one
Can you do a review
Amazing video and keep it up man!
i tried to do that but i did not have any film canisters. BTW i like what you do. Over 20 feet is high ! Very cool !
I ended up building a 2ft saturn style rocket like this in gade school, cool to see someone else taking things too far.
Knoptop!!!!! Woo Hoo!
Peter, I thought it was neat that you took more of a scientific approach to this and experimented with different variables and rockets!
6:05 me when trying to explain something to my teacher
Make a mortar using pressurized air, which shoots anything you drop into it.
You should build a small bipropellant engine. With the goal of real mach diamonds on a small scale. Something like a highend desk toy.
Good work boys
Loved it
Awesome video! I always appreciate your creativeness. Have you guys ever heard of water rockets? Generally they Composed of plastic pop bottles and a bit of high-pressure air. Would be a great project for your channel! Happy New Year’s guys! Keep up the great work
make a 2 stage rocket out of this! that would be awsome
Peter you should make an air matress hovercraft or like a swamp boat with that big prop on the back or an air matress quadcopter that be cool to
Is this an scx10 ii body on the bottom left at the end of the video?

Nice job Sam!
What happend to the mk2 plane
Where do you find film canisters?
You can find them where you can find almost everything....
Amazon has a 60 pack for $17.80, at it's even prime.
Grandma's cupboard.
Until today, I had never in my life seen a clear film canister. They were always black with a gray lid. I figured that was to help keep out stray light.
@@Psychlist1972 We used to have tonnes of them in various colours (mostly transparent like Peter's) in our arts and crafts box (known as the Useful Things Box).
Pete Brown Fujifilm is the one that uses the tighter sealing canisters.
Another great video from PeterSripol
Can you make a roket with the same thing that you did for the nerf?
I heard one of the songs you use during montages in a coffee shop yesterday and immediately knew where it was from. Just wanted to share.
I want to see a multi stage Alka seltzer rocket
good job sam!!
Why do you use the metric system for calculating the amount of water and the imperial system for the height? Wouldn't it make sense to use metric for both?
Love your vids
Yeah but what happens if you increase the friction fit between the cap and the canister?
Random idea: Small version of Panama canal.
Hey I have been watching your videos for a while now and I have to say your videos are my inspiration for studying and creating new.. stuff.
Thank you, Peter!
Napalm bombs for a rc plane!!! Love the vid. Keep up the good work and commentary.
I LOVE the smell of NAPALM in the morning!!
Can you make a pizza bomber from a cheap artf foam to dispense whole pizzas
Here's a hint how to expand on Sam's idea legally without the external pressure chamber: Figure out a way to clamp the container and lid together so that you can get the pressure much higher than the point where the lid would normally pop off. Let the pressure build and then release your clamp.
for the gyroscopic canister it may help to crush/powderise the alka selzer before adding it to the mix. in theory if you do this the alka seltzer will follow the water and stay on the sides as well. making them dissolve together like you need, rather than a heavy round pill that will tumble around in the canister.
Off topic, but does anyone know what motors Peter used in his Flying Sled video? Or what batteries he used? Or ESC? or props? I know, it's a lot of questions
I have done that little experiment at school we did like five in one can thing
Where did you get film containers these days?
I would love to see you revisit David's edf afterburner. I'm about to start building one inside the ft Viggen.
spin sanding, smart!
I wonder if it would be possible to do two things: 1) scale up by a factor of 10 to 100 and 2) with the larger scale, it may be possible take Sam's idea of storing the pressure but this time store it inside of the actual rocket. So maybe there would be some alka selter tablets that get sealed in to the fuel tank ahead of time, and then a valve so that you could feed the water in right before launch, and then a mechanism to disconnect the water.
low cost but fun, me likes,
Where does he get that from I can't find it
9:42 Any of you guys remember that level in Super Mario Sunshine when you had to shoot those Bowser Jr balloons in Pinna Park? Well Peter's rocket reminds me of the rockets in that level.
That's my definition of a rocket..... Rocket launcher
2:15 thats what I say when I am doing something else and a petersripol video pops up, lol who cares what I was doing anyway
It would be cool to see a different competition where you have to build a rocket that uses 1 alca Seltzer tab as fuel, but can be made out of anything. You could do your own pressure vessel, exhaust nozzle, etc.
Make a pressure vessel that contains the alka-seltzer reaction and diverts it through a flow divider to two nozzles set to power a set of helicopter blades by thrusting from the tips.
