Rocket Film Canisters

We've used these with alka seltzer for a science experiment. No leakage. Great quality!

I used to go through a lot of 35mm film and had dozens of the little plastic bottles laying around. I used them for small collections of nails, screws and other hardware kits. The bad part was they usually had a strong ammonia-like smell from the film that was shipped in them. The new ones are clean and have no odor. Great for beads, hardware, etc. They are air-tight and very durable. It would be easier to store them if they are square, but I just rubber band then in small groups.

These absolutely take the place of scouring for old film canisters when completing the Alka Seltzer + water launch! I’m so happy to have a full bag of new canisters to complete this favorite science experiment.

In order to make the canisters work, I had to put a layer of para-film between lid and mouth. Less leakage. How is it that bona fide film canisters, now rarer then hens teeth, work so much better than these, which are designated for this use???,

I used as a party favor and show the kids how to do the rocket best party game. kids had lots of fun and were playing for hours with it.

Just buy basic film canisters. These are no different and are overpriced for the quantity. Don't include any extras like rocket templates like I thought they would.

I bought these to use with a scout group to set off Alka Seltzer rockets. The caps fit tightly and they worked exactly as expected. The scouts had a great time learning how the ratios of water to tablets affected how high the rockets flew.

The seal on this film canister is amazing. There are some bad reveiws, but these are great,My alka seltzer rockets went at lest 30 feet high.
