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.

[@andytaylor1588]

[@skybugproductions7527]

Absolutely.

[@reggiep75]

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.

[@texmex9721]

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.

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.

[@RCOverKill]

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.

[@roelvian]

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.

[@RCOverKill]

@@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.

[@roelvian]

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. the contest: Rocket Contest

[@Nuovoswiss]

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.

[@bloodyricho1]

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

[@userPrehistoricman]

[@cityheron7106]

[@demianmoody148]

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

[@kurtflint64]

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.

[@polluxstar8822]

4:06 just drill holes into the side for every canister length, wouldn’t that equalize the pressure?

[@Bumblebee0217]

[@vreference]

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.

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

[@TheHavnmonkey]

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.

[@chiparooo]

Cool creative thinking exercise!

[@athomeinventions7266]

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.

[@mitchamus]

As the thrust is determined by the pop-strength of the film canister lid... its doesn't matter what amount of water you use. Its like blowing up a balloon with Argon or Air... It still pops at the same pressure

[@donaldburkhard7932]

Use burst discs so when gets to certain pressure then let's go. Or dish inside of container for creating gas, then small hole in container bottom to let gas propel rocket. Keep propellant in rocket. Combination of both?

[@aserta]

Heat the can's end and using a wooden form push the bottom in to a cone. Take another can, cut the bottom, throw it away, cut the tube in 3 equal parts, bend them with the natural bend on the outside, then glue those fins to the formed can, shape to desired form.

[@USWaterRockets]

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.

[@EnderMalcolm]

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.)

[@weld4200]

[@Elias-cb9nm]

What happend to the mk2 plane

[@derricrogala9480]

You could use double sided tape to tape the alka salzer to stick on the side so when it spins the water will run along the side of the container and keep constant Interaction with the alka salzer. It might work but yet again I’m not sure if I’m understanding the problem lol

[@Madnessnunky]

A multi-chamber seltzer rocket with a blowout valve that only opens once a certain pressure is attained would be best. More chambers feeding into the output with a plug that breaks at operating levels will maximize gas production and consistent output over a greater duration. Essentially: output nozzle on bottom, main combining chamber above with rubber plug to blow out at maximum pressure. (output diameter TBD) Various fuel tanks on sides directly attached with tubes to increase gas production into main chamber. Bonus: Staging could be accomplished via a small compartment on top. A seltzer tablet affixed to the "roof" of the container with a weak bonding agent will fall and begin to mix right at the point of liftoff. After the bottom stage decelerates and falls away, pressure will release the upper stage for a short burst flight at max elevation.

[@meronamsamho9410]

put like the hard part of a q tip in the center of the canister poiting directly upwars, drill small hole in center of tablet and place tablets onto the q tip to keep the stable

[@runvnc208]

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.

[@christianjohnson1416]

When you said the pressure has to equalize in the tube why wouldn’t you shorten it but add hole on the bottom to equalize the pressure

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.
