Bob, thanks for bringing great memories back! I still remember the competitions we had as early teens on who could hold metal bars the longest, from an electrical manual crank generator. We would use an additional wire string with 2" nails at ends to complete a series circuit between 2 players, and whomever let go first will be discualified. Those were my first "fun" days with electric circuits. LOL

My thoughts went to my high school electronics teacher 35-or-so years ago who was tired of one particular student always touching everything on his desk. This problem was solved by a charged capacitor left on his desk before he left the room one day..... Ah, those were the days......

There's a rather more boring demo of this here: http://www.primitiveways.com/chemical_fire.html

A lot has happened in those 34 years. And not all of it is good.

of course that was 34 years ago. These days he'd get arrested for child abuse....

ah, yes, electrical shocks. My high school electronics teacher once asked my class of a dozen or so seventeen year old boys to stand up and hold hands. This was not a popular thing to do. He was holding a small box in his hands, and gave a stripped wire to a boy on each end of the group. With a chuckle and a smirk he flipped a switch, and the bunch of us yelped like little girls. He laughed about that through the entire class period. Good stuff.

Wow. You guys are sick. (Hey, where do I get some of those Condie's Crystals, anyhow?)

Speaking of fire (Condie's Crystals) and toys, growing up I had neighbors that would take their plastic model airplanes while the glue was still wet, light them, then toss them from an accessible flat roof to let them have a flaming "crash landing" in their back yard. Being non-aerodynamic with no source of power after launch, crash land was about all they could do. The kids would gather the pieces, glue them back together, and repeat.

Another experiment with Barbies: remove head, fill head with Condie's Crystals, add 2 or 3 drops of glycerin. Reattach head and throw! Someday I may tell my kids about that. Maybe.
