Tim Peake talks about the need for his spacesuit to keep him alive when outside the International Space Station. Space is a hostile environment, and the spacesuits are constructed from a tough material that allows the astronauts to survive massive temperature changes. The suits also allow the astronauts to breathe and it regulates the pressure around their body. Fran Scott demonstrates using a marshmallow man how air pressure is very different on Earth than compared to space.

Could be used to engage pupils with the current mission to the International Space Station focusing on British astronaut Tim Peake. Spacesuit construction could be examined and why astronauts need to wear them to keep them alive.
