Aluminum base, chamber shooter

Unread postAuthor: willarddaniels » Fri Mar 16, 2007 10:51 pm

I figure the title might seem a bit misleading, but that is what this thing is. The pics explain most of it...
Fit a normal 1 litre or 2 litre bottle over the nozzle with the two o-rings (lubricated) and slide the keeper over the flare. Pressurize, pull on rope to let 'er fly. Height of projectile corresponded fairly closely to psi: 40 psi = 40 feet. This was almost always shot straight up.
Pressure ranges: 10 - 100 psi
The higher the pressure, the higher the chamber went. Not a single bottle burst on us, although 3 got stuck on the roof and one in the top of a very tall tree.

I taught my 4 and 6 year old how to operate it and then I went back to rototilling the garden, this way I could supervise their "playing".
While they were busy blasting away, my friend's 16 year-old boy drove by and stopped to see what crazy things we were doing now. **Proud papa moment** My older son explained to him exactly what they were doing and exactly how and why it worked so well. He used (properly) some terms: compressor, compressed air, trigger, releases, air hose, pressure, etc. to explain it to a kid 10 years his senior! They talked about it for a few minutes like they were buds in shop or ag class together. It was pretty dang funny to watch. He helps when I tinker in the shop, but I didn't know he was absorbing so much.

Cool. So this is just like a bottle rocket? Have you tried filling the bottles 1/3 full of water, it makes them go way higher

Not yet... the high school science/physics class did that last spring. I'll have to try that in a few weeks when we bust it out again.
