taco bell cannon

Unread postAuthor: chrissilvermancs » Sat Apr 04, 2009 11:49 pm

made this in 10mins got board, and noticed the shape of the cup and had a idea.

this cannon is the large plastic cup with the original plastic top taped on.

i shoved in a 1" piece of pcv in the straw hole and taped it on with masking tape

the spark is done by a tazer and a long cord to two screws that i had screwed into the cup

the projectile is a pencil with some tape around it for a better seel

it is powered by propane but i didn't bother to do the metering math because it would only last a few shots so i filled it with propane all the way and squeezed it a couple times and the last shot was the best. the one i have on video sorry bad camera.

Looks like it's a little too powerful... Any chance of better pictures?

sorry on the pictures i just screen shoted the video and cut it so size but theres nothing to it but paper thin plastic two screws and alot of tape 9masking tape at that) and that piece of pvc i shoved in and called a barrel.

i was surprised it didnt just explode i was actually hoping for something catastrophic hence the trash can and Plexiglas shield i was behind.

then i just burnt it to a crisp with a flame thrower when the top broke that why i cant get u better pics sorry
