CREATE AND LAUNCH YOUR OWN ROCKET AND CHALLENGE YOUR FRIENDS TO SEE WHOSE CAN GO THE HIGHEST!
(This activity should be done outside, depending on the height of the ceiling of the room that you are in. Note also that there may be asbestos or other issues such as projectors or lights with the ceiling that may prevent launch indoors).
The Vitamin C tablets are effervescent. They dissolve in water and produce a gas (carbon dioxide), which is what causes the fizzing. When the lid is on the canister, the gas has no escape route. The pressure inside the canister builds up until the top part is forced off, upwards, at high speed.
HEALTH AND SAFETY
Please ensure that the children stand back from the canisters at a safe distance to prevent being hit.
Children who also have sensitive skin are advised to wear gloves.
