Don't open the bottle

Don't open the bottle

A hole is placed in the side of a full bottle of water but mysteriously no water escapes - until the lid is opened. In this lessons students use ideas about atmospheric pressure and the skill of constructing explanations to figure out how the trick works.

Learning objective

  • Communicate ideas: Use force diagrams to show how the mystery works.
  • Pressure: Explain how the mystery works in terms of the effects of unequal force.

    • Unit: Heating & cooling
    • Concept: Pressure: Particle motion causes gases to produce pressure on the containers, which depends on their temperature
    • Skills: Write: Use diagrams to communicate
    • Learning stage: Acquire
