Educational outdoor science activity.
Build some film canister rockets. We have had so much fun launching film canister rockets! It is wonderful fun to see who can design their rocket to go the highest. All that is needed are some empty film canisters, a few Alka Seltzer tablets, and some water. Yes, finding film canisters can be a little challenging these days, but if you cannot get any donated from your local store, you can get them online at http://www.filmcanisterrockets.com Sure to be a hit with all the kids (and adults!). Have fun!
