@Wilso,
Yep, a day I was bored I made one of these myself.

It was funny but limited so I replaced the battery with a small solar panel and changed the RPMs by changing the panel's orientation re the sun.

@timur,
we used to paint ammonium triiodide along doorways at the labs. Mix it with a bit of lard and itll keep from going off till its struck

Its a beautiful smoke that shouldn't be inhaled (its not a strong oxidizer like Cl)

This is what i originally went looking for when i found that last video. This one is really cool to show little kids, who can safely make salt trees with a supersaturated saline . . .

@Setanta,
Amazing, yes. In particular the speed at which the reaction took place in the first vid after she dropped the single crystal into the soln. I didn't expect that.
