Wow forgot about cap firing rockets - I can still smell the caps!

Oh, Carbide Gun? That reminds me that we used to get an old Ovaltine (Chocolate type hot drink powder) tin, pop a small hole in the side near the bottom. pour in a little water followed by some carbide then jamb a tennis ball into the mouth of the can. Balance the lot against the edge of a house brick to get elevation the a lit match to the hole and whoomp. Tennis ball some 50 metre down the back yard. The reason for the Ovaltine tin was because it was just the right size for the tennnis ball to fit. Kinda handy living in a town where mines still operated so carbide was fairly easy to come by.
:offtopic: Hey what was the topic again? Oh yeah, Weekend projects.

BLAM BANG, The tram brakes slammed on and the poor dirver got out to see what he had hit or what had blown up. Two boys sitting on the fence trying not to laugh. Oh and what about two half inch bolts part threaded into one nut with the gap between stuffed with match heads. Tossed at the brick wall. Amazingly I still have all my fingers, eyes, etc.

You were lucky for sure pioneering the pipe b. It is amazing just how much energy matches have.
