Backyard science---Daniel + a film canister + baking soda + vinegar = a rocket that shoots 20 feet into the air, just be careful of the vinegar trail it leaves on the audience...
Hi Rebecca, We are all digital here also, so I just asked at the Wal-mart photo developing counter and they gave me a handful. Probably any place that develops film would have some to give away. It was a fun experiment, although it did take a while to get the quantities correct---it took a lot less of vinegar and baking soda than we thought.
Very Cool!!! Where can you get film canisters for those of us who are completely digital now?
