Hooked On Science – Launch a Canister Into the Sky
PLEASE follow these safety precautions when doing any science experiment.
• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything while doing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
• Film Canister
STEP 1: Fill the film canister half of the way with water. Describe and classify the water by its observable properties.
STEP 2: Place an Alka-Seltzer tablet into the film canister, snap on the lid, quickly flip the film canister upside down, and observe. Describe and classify the Alka-Seltzer tablet by its observable properties. Does adding water to the Alka-Seltzer tablet result in a new substance?
When the water and Alka-Seltzer mix, in the film canister, a chemical reaction happens, creating carbon dioxide gas. The carbon dioxide gas fills the film canister until the lid and canister separate, forcing the film canister into the air.
