I prefer a 50 gal trashbag full of acetylene and oxygen.

Nuclear purple flash, a bang that'll echo for 10 seconds (at least in
the hudson valley), surprisingly little destructive power, and no
evidence except tiny bits of melted plastic.

I was thinking, buy 3-4 helium balloons, tie one balloon full of O/A
to them, add a fuse, light the fuse and let it fly up in the air
before exploding. Kids might like it.

Don't. If you want to fuss around with
acetylene, get some calcium carbide and
play with it.
