Whether they are breaking the atmosphere into space or soaring through the sky here on Earth, all rockets are launched into the air by the generation of thrust. In this experiment you can launch your own home-made rocket and rocket fuel using everyday things around the house.
As with any explosive experiment, make sure you have a grown up handy for this one.
Houston, we have no problem!
Would more water effect how fast or high the rocket flies?
What effect would adding the whole Alka-Seltzer tablet have?
When the Alka-Seltzer is added to the water it generates a gas called carbon-dioxide – the same gas that gives fizzy drinks their fizz. As more gas is generated in the small, airtight space of the canister, an intense amount of pressure is created. This pressure creates the thrust that blasts the cap down and launches the canister into the air.
Despite being a gas, carbon dioxide is nothing to worry about. It is not poisonous and plants absorb it.
We like to think that the UK's original science party is still the best.
But we'd never let you take our word for it.
