My Girl Scout troop hosted a Science event a few months back. One of the
activities was building and launching rockets. Everyone really enjoyed this,
and several of the leaders and moms present who were also Cub Scout leaders
took the idea to their dens. They report that the boys loved it as well.
Take a toiler paper tube and mark a spot 1" from the end. Cut five slits up to
that spot and fold the slits out (this forms the base of the rocket launcher).
Take a paper plate (or a plastic plate) and tape down the toiler paper tube
(with the "legs" out flat). Decorate with markers, stickers, etc. if desired.
Take this outside. Your 'rocket' is a 35mm film canister. The clear ones work
best, but the black ones will do fine. The best ones are the ones with the cap
that fits INSIDE the canister. (Hmmm, this is hard to describe without you
seeing my hand motions!).
Fill the canister about 1/3 full of water (part of our activity was
experimenting with how much water to use; started with half-full; then almost
full; then about 1/3 full). Take 1/4 tablet of Alka-Seltzer (or equivalent
store brand) and drop into canister. Put the lid on tightly and place LID DOWN
into the toilet paper tube. Step back. It takes about 1 minute or so for the
rocket to launch, but we achieved some pretty impressive heights!
Any place that does film processing will GLADLY give you as many film canisters
as you are willing to cart off. K-Mart and Wal-Mart both were generous, but
the best place was a local film developing store that had LOTS of the Fuji film
canisters (these are the clear ones with the 'inside fitting' lid).
We got this idea from the January 1995 issue of _Family Fun_ magazine.
