Carl,
I like that KCLO3 and Aluminum dust "ejection" charge.
Several individuals I know experimented with similar mixtures way back when I was in high school with quite entertaining results.
SHOULD still be perfectly legal to do so now with ZERO permits/licenses.

Nowadays unless you have 47 explosive licenses and permits through BATFE, CPSC, local and state fire marshals, police chiefs and sheriffs, environmental agencies and other various useless nonsense agencies, you will be charged with some sort of terrorism. My grandfather (now deceased), father, and several uncles can remember being able to go to local hardware stores to buy actual DYNAMITE for blastin' stumps, etc. without ANY sort of permit, you just had to sign for it. After that stopped, most farms I knew of used ANFO for stump removal.
