Calcium Carbide. as in "limelight" or miners lamps "fuel" mix with water and it produces acetylene gas as in what Union Carbide made.

Ahh, I see.

I was wondering because I deal with a lot of carbide tooling, and alot of times it is water-cooled when turning or milling something. I never noticed any toxic gas or anything being given off that would cause it to explode:confused2:

Thanks for the heads up Brin.

I remember when I was in High school we made similar concoctions in chemistry class,. We used the "mixes" to blast off a rocket we also had made. Different mixtures had different "explode times, and some really got the rocket moving too.

I do remember baking soda, vinegar and tin being common, in fact, there used to be a rocket kit with that almost that mix as the propellent sold. heres one that looks similar to ones I. remember.

Of course, kids in my day didn't do "drive by's " either.

THats been going around since the late 90's. my brother showed me how to make them in about 94. The first one I made I used too much works and not enough foil and it took 3 hours to go off. I had forgot about it and dad was asleep in his chair. I was out in the backyard shop and the thing went off in the ditch. I roun outside the shop and looked at the transformer, dad ran outside looking at me and the shop and in not so many clean words iwas ordere not to build another one.


We were building a development for a company we worked for. I was running one or our scrapers and we had 2 rented scrapers. We started out throwing water balloons at each other meeting on the haul road. Then one cat threw a dead snake at me. I made a works bomb out of a 2 liter bottle and chucked it in the scraper bowl on my buddies Terex as he left dinner break. He almost got out of the seat. We had a science teacher in HS that made them in a glass open bottle. He would put balloons over the opening and fill them with hydrogen gas.


Well on day he made one and didnt like the fumes so after he thought it was cooled he put a lid on it and put it in the trash. The next class almost pinched holes in their seats.
