has anyone tried launching projectiles with FP CO2
I was asked to leave my hall of residence at Newcastle in 1987 after such an experiment!

Excerpt from security log:
Approx 00.40hrs caught Mr. Rafferty in the quadrangle with a CO2 extinguisher in which one can see he has a plastic tube attached to the nozzle. Mr Rafferty was experimenting with it by shooting plastic film canisters from the tube

It went bloody well - particularly with the nozzle restriction removed and shot the film can several hundred feet in the air (based on time delay).

I would not reccomend you try exactly this, or at least dont get caught, but I felt it was a worthwhile experiment!

a bit like my spud gun then.

And my aunty has seen it in action - check my profile

This year I built a compressed air gun which fired a D cell battery clean through my garage door. It used a fairly novel shuttle valve - bit like a poppet valve where you release the pressure on one side of the valve and the air pressure itself opens the valve to achieve the max possible airflow from the reservoir to the barrel.

Decided it was a bit dangerous and filed it in my dangerous things pile ;-)

Bit like a spud gun!

Sorry for not speaking clearly.....
Of course I was interested in possible robotwars application of a CO2-launcher....

And, well, sorry for hijacking thread too....
