marshmallow cannon

Well I thought I might as well share with you all my engineering project that I did a few months back. It’s a marshmallow cannon made out of pvc, steel braided line, tippmann 98 asa, and a 20oz tank. The project was a contest at UCF my team had to make a device that shot a marshmallow 50ft to land on a paper plate, it also had to cost under 25 bucks (used 4oz pre-filled when in the contest to meet the price limit). To shoot it you simple turn the tank into the asa as fast as you can…not really inventive but I was trying to make it cheap. After a few test it worked really well and I found that if you turn the tank fast enough into the asa then the Co2 will freeze the marshmallow solid and put a pretty big hole right threw the middle. It also proved to be a pretty good fire extinguisher…

oh and HOBOTASTIC 2 is its name.

that looks cool... Iwant it

Nice.  You should somehow cut a slot for a stop with a hole in it somewhere that is covered when you have it out, but then when you push it down, you let the CO2 out of the hole and it pushes the marshmallow out.  That way it's faster and you won't blow O-Rings as easy.

I’m in high school but taking a college class called "intro to engineering 1& 2" its part of the magnet program I’m in.

amazing could you possibly give us instructions please

nice! I love it...nothing like school projects

cr125 or 250? i like bike and the launcher

Ahm'a makin maslf one o them!!!

gotta make one and by the way nice dirtbike
