C'mon! A little common sense and the kids would have been instructed to stand at lease 10 ft back from a tape line, row of rocks or whatever. We had, and still have, a blast with those things. The plasic is becoming a little brittle though.

I wasa born in 1962...bummer!!

Where was this when I was a kid?? All I got to play with in the 70's were some reactive metal salts, weak acids and some basic (>pH 7.0) chemicals...nothing like a bubble chamber!

I got this for my 4 year old daughter in 95. What a blast!! I think I had more fun with it than she did. neither she nor I were ever injured or hurt in any way.

Through the 70's, I was given, every 4th of July, a calcium carbide cannon that was sold at most fireworks stands. This item needed to have powdered calcium carbide placed into the chamber of a hollowed out tube (cannon)and then have a small amount of water added to it, liberating acetylene gas! Stinky, poisonous and soo much fun! Then a Bic lighter like type device was used to ignite the mixture of air and acetylene....Kappoww!!!
I never was hurt, injured anyone else or started a fire.
great memories!!

In 1968 I was 7. I received this toy with a stern warning from my dad about the heat and to read the instructions, which I did.

I never got burned and had a blast!
