Last time we checked, rocket fuel is still a no-go in the classroom, and that's why Flying Film Canisters are so cool! A simple mixture of our Flat Fizzers and water results in an explosive, rocketing film canister that would make NASA jealous. These plastic, super-sturdy canisters are the best we've ever seen, specially made for Steve Spangler Science to ensure the biggest, best pop every time. How much water does it take to create the biggest launch? How much of a Flat Fizzer do you need? You'll have to test mixtures to be sure! Don't settle for regular film canisters that don't give you the pop you need. Get your hands on our Flying Film Canisters and blast off! What Does It Teach? When you have gas building-up in an enclosed space, what happens? Wait don't answer that. More specifically, what happens when CO2 builds up in a closed film canister? Simple – an explosion so fun you won't want the popping to stop. The key to the fun is our Flat Fizzers. These tablets are made of sodium bicarbonate (baking soda) and citric acid. These non-toxic components dissolve and mix in water, creating carbon dioxide. The gas is too much to contain in the closed canister and it builds until: 3 2 1 You know the rest.
