A Rocket Made of Kitty Litter and Sugar? Yes, Really.
Do you want to get creative for less 50 cents? You can make a rocket made of kitty litter and sugar that shoots over 2,300 feet high!
Please read their words of caution to anybody interested in making these: Although the project video shows step-by-step how to build the motors, I would caution anyone wanting to make one to take precautions. These are not toys. They can light things on fire, and fall down on peoples heads, which I imagine could cause serious injury. You may need permits, or only be able to launch these on special experimental launch days with local rocketry clubs.
