Fran Scott demonstrates how rockets lift off during a launch into space. This is how British astronaut, Tim Peake has managed to reach the International Space Station. Scientists and engineers work together to use combustion reactions to release large amounts of energy, which create a specific force known as thrust to oppose gravity and allow the rocket to lift off. She demonstrates a small combustion reaction using a hydrogen filled balloon and oxygen in the air. This reaction is then increased by incorporating hydrogen and pure oxygen in a balloon, before setting fire to it. The resulting fire balls and explosions are impressive.

Could be used to engage pupils with the current mission to the International Space Station focusing on British astronaut Tim Peake. This demonstrates how a simple combustion reaction can be used to create thrust used in rockets.
