Match heads! That pops a memory bubble.

Had a 2 ft pc of brass pipe. End cut off with a tubing cutter so it
was flared in on one end. Popped the gizmo out of the end of CO2
cartridges. PACKED in match heads cut from matchbooks. Wire cutters
were the bad- asses tool for this exercise. Towards it being filled,
put in a firecracker wick. Packed a few more heads in. Drop CO2
cartridge in pipe wick end first. Stops nicely with wick exposed out
back end because it's flared inwards. Hold pipe in hands, aim and
light wick (smart ehhh]. Thing would launch with a boom & flash. Cool
at night. Used to aim it across the river at the marina and listen
for the plunk when cartridge hit. Hear the people on the boats
sitting around getting drunk yelling "Hey you ****in' kids!" Laugh
asses off...so they could hear.

This was living...

We used equal parts of powdered zinc and sulfur.
