It had its time, it had its space, but I cant leave this alone. citadelofmyths.freeforums.net/thread/475/supersonic-ping-pong-ballI have an idea just so crazy it just might work. This was originally done in just a vacuum tube..... Ti "Fire", you just pierce the end the ball is sat at, and atmospheric pressure does the rest.... Now I am wondering, if the end you pierce was under pressure? Instead of a piece of plastic, a Gate valve. On one side a vacuum, on the other, a pressurised tank.... |

Its quite simple.
(Well, in my mind it is?...)
(And who knows what goes on in there.......)
Take one chicken cannon, which I believe is a gate valve pressure release.
Fire, measure the speed of flight.....
{Squarrrrrrrrrk-splut...)
Repeat, but this time, seal the end of cannon with shrink-wrap, and pump the air out....
I expect a few less r's in the squarrrk....?....

The only problem I can see with your plan is friction, but Jamie & Adam can always use some of Jamie's favourite building material - LARD!  to overcome that problem. Mind you if they don't use enough lube you may get a few more "r's" out of that ball as it 'fly's' down the tube than you did with the chicken.  |
