Here's an easy science project that was a big hit with the Bubs.
1. Cut a 4 inch piece of straw and a 4 foot piece of fishing line.
2. Put the straw on the line.
3. Tie the fishing line (plenty of that around here...) to two chairs, pulling it tight.4. Blow up a balloon, but don't tie it closed. Just twist it slightly.
5. Using masking tape, tape the balloon to the straw.
6. Let go!!
7. Chase it down and giggle with delight. :)
This experiment demonstrates
Newton's Third Law of Motion because the air blows one direction, and the balloon goes the other.
Looks like fun! We found a lot of fun ideas in the Cub Scout Manuals. We made tin can stilts, rock crystal candy, and pet rocks.
