Hmmm. Reminds me of some of the fun one can have after Chem Lab. Potassium Tri-Iodide is fun. So is metallic Sodium.
The problem with my teen-years' uses of these is that they were addressed "To whom it may concern", which I now realize is un-cool.
What I want are the micro-caps and the RC detonator...
Hmmm, again. If I mount six sticks of dynamite side-by-side on a board, and set this target out at, say, 300 yards, it would be a readily-known event if I could hit it with a bullet. Hmmm...Hang a few from strings, paint them up, and tell somebody it's a new style of wind-chime?
Sincerely, Sick'n'twisted
