Flying rocket experiment

Students had fun today with flying rocket experiment. Conducted this activity to introduce reaction of acid with carbonate.

Add sprite in film canister, to about 3/4.
Add 3 spatulaful of baking soda on the cap.
Place the cap over the film canister and shut it tight.
Invert the film canister.
Step away and watch it launch!

Sprite can be replaced with coke or vinegar.
Baking soda can be replaced with antacid tablet.
