Oh, rockets, kgbsquirrel, I almost forgot.
As a kid I made rockets out of the cardboard tubes they used on clothes hangers with plaster nozzles which blew off >50% of the time, with homemade black powder. Saltpeter from a local butcher, no questions asked, sulphur from a drugstore, always asked what for, always said my mom wanted it to repel mice and rats, but transaction completed with a funny look, confessed this sin of lying next Saturday at Confession.
I quit when one landed still smoking in the rain gutter of the house next door and I sweated it out for a half hour hoping I didn't start a fire up there.
But, no fire, no Sin, no Confession.
