No Pressure

Ever wondered what would happen to your body in space? This activity will give you some idea. It shows how a marshmallow expands dramatically when normal atmospheric pressure is reduced, so students can understand what would happen to a human body in its place.

Learning outcomes:

  • Investigate how materials behave when atmospheric pressure is changed
  • Use observation and questioning (curiosity) skills
  • See how forces and atmospheric pressure have useful and relevant applications in our everyday lives
