ADVICE

Egg Spin Test

  • Spin a raw and a boiled egg to tell them apart.
  • Stop each egg briefly; the raw egg will continue spinning due to the liquid inside.
INSIGHT

Physics in Action

  • The same physics principle governs spinning eggs and the Hubble Space Telescope's gyroscopes.
  • Everyday physics offers simple laws applicable to complex technologies.
ANECDOTE

Egg in a Bottle

  • Helen Czerski describes an experiment to get a peeled, boiled egg into a bottle with a smaller neck.
  • It involves air pressure changes caused by a burning match inside the bottle.
