When I was 12 I was using potassium nitrate and sugar as "rocket fuel" for CO2 cartridge rockets. (Note to readers - I was lucky not to lose body parts).

Not sure what the kitty litter is for. Moderator? (no, the -other- kind of "moderator").

I also used soap and gasoline on toy boats It was kind of a Greek Fire inspired kind of thing.

Techie kids across the country have been playing with this stuff for longer than you have been alive. You can probably double that length of time.

You just need to talk to the right group of 12 year olds. @:-)

There are adults in this country routinely launching privately built rockets miles into the sky. Explosively forming sheet metal into works of art and hundreds of other things that go :-:boom:-: in various and interesting ways.

Ahmed Abdellatif Sherif Mohamed and his kitty litter is not a good argument on which to hang your hat.
