NASA has a great little project online to keep the children busy over the holidays. how to build a paper rocket that really takes off using fizzing tablets, such as Alkaseltzer antacids.

You’ll need the following materials:

* Paper, regular 8-1/2- by 11-inch paper, such as computer printer paper or even notebook paper.
* Plastic 35-mm film canister (see hints below)
* Cellophane tape
* Scissors
* Effervescing (fizzing) antacid tablet (the kind used to settle an upset stomach)
* Paper towels
* Water
* Eye protection (like eye glasses, sun glasses, or safety glasses)

See how to, at NASA Space Place.
