This was a much needed video after the assembly line cranked out 30 rocket motors here at the house! Now the kids can launch their rockets without lighting a fuse(which we made from your tutorial)! Thanks a million!
This was a great tutorial. I did find that Dole pineapple chunk cans (20 ounce can in water) works the same way as the Progresso soup can. I was worried about vent hole size since some sites say 3/4". I went with 3/8" and 1/4" holes and they work great. THANKS!
