I was just watching the chicken gun myth episode as well... its a cool gun, but still if someone posted that gun on Spudfiles, it would get ripped apart :lol: . The perpendicular construction creates stress on the barrel (though they do have that stand), the chamber to barrel ratio is off, the valve should have not been manual, the barrel was too short, etc...

Rmich, same thing with that cannonball cannon. they used un-modified solenoids for gods sake! if you heard the thing dry-fire it went FSSSSSSTTTTT BLAM!!!! just like an unmodified sprinkler valve. i still say the mythbusters should have consulted BTB, their cannon would have OWNED. either that or made a hybrid, but i dont think discovery would like the mythbusters explaining to random ppl who watch TV how a hybrid works.... many deaths would follow.........

Heh.. I'll give you a cookie if you can guess the only mythbusters episode I've never seen.

I thought the ninja ones kinda sucked too, unfortunately. I wish adam would post the chicken gun here actually :)

yeah. someone shold send in a request for the mythbusters gang to get an account on spudfiles. so many things they do on that show could be severley bettered by the spudfiles community. we would also like to see what a 100,000 dollar budget per cannon would make.............

yup, i noticed that the first time i watched the episode, and for about 2 days afterward i wondered what it would have been like with a piston valve :D

The Mythbusters do have a budget though... they were pretty good scavengers for that project. Anyways, I think the main problem with the chicken gun was the inaccuracies which resulted from the different times which it took to open the valve. A piston valve of that size (while certainly feasible with their tools) would cost too much.

...Though, aren't they the ones who wasted $25,000 on ping pong balls :lol: :P :shock:

WTF?? How many pingpong balls did they need!?!? What for?? Anyways, I think that their budget was definitely enough to facilitate a good cannon of that size. I mean, really, 2 grand should be more than enough.

They Used the Ping-Pong Balls to lift a ship out of "Davy-Jone's Locker". It actually worked..........

and yes, 2 grand could make me a 6 inch porting piston valve. who the hell WOULDNT want a 6 inch porting piston valve. of course, youd have to vent it with like a mauler vented by a QEV to get ANY kind of power but hey......... Not my problem. In fact, i might have won 7,000 bucks for some cheapy car sweepsates thing. if i did, you might see a 6 inch porting valve............. MUAHAHAHAHAHAHA

Yea, I've seen video of some MIT students making a steam cannon better than the mythbusters though, dang it owned. But they said it was so powerful they weren't going to release the inforamtion on how to make it. Oh but it was powerful. I've been trying to figure out how they did it.

The steam cannon was pretty impressive. Adam and Jamie were really surprised that the cannon ball traveled a mile, but the pressure chamber was massive! If they had taken the cannon up to 200psi like they had originally planned, they would have put that cannon ball into the city of San Fransisco.

The small scale 2nd generation steam cannon was something I would love to build.

I know how they did it - but I'm not going to tell you either, because I'm evil. :twisted:

That, and I want to build one, but my parents certainly wouldn't approve.
