lol - great story. So many good stories here about this stuff.

I agree with others who say it's dangerous, but only if you use sufficient quantities, or contained (don't contain!). A few crystals sprinkled in different places will just produce the pops and not hurt anything - I think! :)

From memory: size of a full stop or white sesame seed will already produce a very (but not painfully) loud bang; whereas a speck so tiny on the ground you can't readily see it from standing height is sufficient for a "walking over" prank, surprisingly loud for how tiny it is.

The ultrafast snappy pop and purple smoke is satisfying, but it does stain.

I like the comment about ping pong - hilarious use case.
