Me too. Better bang in coffee or Pringles cans!

Built a carbide cannon out of pipe for a science fair project! It shot D cell batteries perfectly!

An example of my childhood: Can of calcium carbide pellets. Rainy day puddles in the street. Matches.

We used a coffee can or a paint can and the lid was our projectile. We used a nail to make a hole in the can near the bottom, put the carbide in, spit on the carbide, put the lid on, angled the can on a brick or a stone, waited a short time, put one foot on the can and then set a match to the hole. The lid went a long way and we are fortunate no one was harmed.
