Rocket Science

Preschoolers may be too young to understand the Third Law of Motion, but they still have a lot of fun watching Alka-Seltzer rockets soar. Forget about paper templates, to make a rocket easy enough for a small child to handle, all you need is:

- clear air-tight plastic canister (e.g. film canister) - rocket's body
- stickers, permanent markers, etc - to decorate your rocket (optional)
- Alka-Seltzer ORIGINAL pill, broken into 4 pieces - rocket fuel
- water
- flat surface in the open area (e.g. driveway, patio) - launch pad

1) Turn your can lid-side down. Decorate the rocket, making sure that you can put the lid on and off easily.
2) Go to your launch pad, make sure there is no breakable things within 6 ft (2 meters) off the launching area.
3) When ready to launch, put 2 tablespoons of water in the rocket, put 1/4 of Alka-Seltzer pill into the water, QUICKLY snap the lid on, turn the rocket right-side up and set it on the launch pad. DO NOT try to pick up your rocket up once you set it down for launch.
4) Step away! Count backwards from 10. And watch your rocket take off.

Once your rocket has launched, collect the rocket, cap and leftover fuel. Clean it up, and it's ready to go again.
