Pascal's Law
For this Rocket Launcher, you will need an empty one quart soda bottle, a cork
that fits it tightly, a paper towel, 1/2 cup water, 1/2 cup vinegar, and 1 Teaspoon
of baking soda. Add streamers for effect, and to see where the cork goes! The
cork is the rocket, so attach the streamers well with a thumbtack. Pour the vinegar
and water into the bottle launcher. Cut the paper towel into a four inch square.
Put the baking soda into the middle of the square. Roll it up and twist the ends
so that the baking soda will stay inside. Make sure that you are outside with
lots of clear air space and not pointed at anyone! Drop the paper towel with the
baking soda into the bottle. Put the cork on as tightly as you can. The liquid
will soak through the paper towel. This creates a gas which will build up pressure
and push out the cork with the thrust similar to a rocket being launched into
outer space!
