AKIRO Film Canisters with Caps 35 mm Empty Camera Reel Storage Containers Case Plastic Storage 15 Pack Transparent

I am an elementary science teacher and bought these canisters for Alka-Seltzer Rockets. They work perfectly for this, as the lids fit tightly and allow the pressure to build up and create high flying rockets (they will bounce off ceiling). The tight fit can be a downside if you are trying to have 2nd graders and below use them, as some may not have the strength to open the canisters themselves. I love bringing the experiment to any class as it is always a fan favorite, and these canisters are partially responsible for how cool the experiment is.

Didn't use for film but as a storage container these worked perfect, glad these are still around!

We purchased this for my son's birthday party where we did science experiments. They kids loved it. They create a great seal, easy to remove and pop back on.

All canisters worked well. Some canisters started to leak after 3 - 5 uses. Overall worked well and good value.

These are the perfect size for containing homemade Firestarter. Collect some lint from the dryer, add Vaseline and just a pinch will ignite immediately from flint and steel that will burn well until the kindling takes off. One container holds at least 6 starts.

I purchased these to put in my diabetic emergency pouch. They hold a weeks supply of lancets, a couple pen needles and keep everything tidy! Its a bit “outside the box” use but its great!

Perfect for a science experiment with the kids. Alka Seltzer and water rockets

We used these in my class to make butter by shaking heavy cream. The lids held tight and the end result was great. Will buy again for my new class this year.
