Year 1 made rockets using a film canister and coloured card to wrap around the tube. We added colourful cones on top and orange fire at the bottom. Adults launched the rockets by pouring a small amount of water into the film canister then adding a special fizzy tablet. The lid was put on tight and then they were set on the table. The adults moved away quickly. The tablet caused carbon dioxide gas to build up in the canister until there was no more room inside. The pressure pushed the lid off and made the rocket shoot into the air.
