How I miss it and the wonderful bombs I made as a teenager in the 60s.

Electrically detonated at the local gravel pit and hours of harmless
fun.

You *were* sophisticated. We filled drinking straws with the mixture,
lit it and ran.

Perhaps that would have read "armless fun" if one of the buggers had
gone off prematurely!

Indeed :-(
