The LaunchIt is an inexpensive and customizable model rocket launching system you can make yourself.
Seeing the Mythbusters setting off pyrotechnics and rocket motors with a drill battery and a couple of wires inspired me to create my own launching system. I’ve been interested in the subject since building and launching Estes rockets as a kid.
