Mini cannon/L.E.D. Launcher
Posted: Tue Sep 11, 2012 11:50 am
In the past I have made tennis ball soup can launchers.and modified to make noise(no projectile)soldering large metal funnels or larger cans at the end trying to get a (visible)vortex ring to come out the end.
This is my first PVC pipe attempt.I was wanting to make a compact flare gun style cannon,with a lantern spark/lighter in the end cap.fuel thru a hole in the T in front of the ignighter.I have been useing alcohol based fuels mostly 100proof vodka.or 91%rubbing alcohol . Vodka smells great after it ignights,)and can't seem to get the air fuel mix right,I had alot of little "Womps" but no real bangs,the small size,is the reason I'm sure. So yeasterday i decied to introduce O/2 into the mix.I have never used pure oxygen and I plug the barrel end with ammo I start filling the chamber with o2 and I let o2 run and run and it flows for a long minute or so.I remember that O2will make things burn twice as fast so I only dump one spray of vodka/91%alcohol mix(about5ml no really5ml)and holy atomic bomb,batman.I may have put a small rubber ball into orbit.
Over all length is 21inches/1 1/4 inch sch40 PVC .my main purpose is to launch LED on the 4th of July and any other time I feel like lighting my BOOM stick.I need to figure a way to more effectively mix fuel air with out dragging an O2tank around.
