Make An
Egg Bounce


  • 1 Egg

  • Glass Cup

  • White Vinegar


  1. Before you start - make a guess on what your egg will look like after 2 days of soaking in vinegar! Why do you think it will look this way?

  2. Fill your glass with enough white vinegar to cover your egg.

  3. Put your egg in the glass and wait for 2 full days!

  4. Pull your egg out and notice the way it feels. Why does it feel that way?

Take Note

  • After the first hour, take note of what your egg looks like. What's happening with the vinegar and the egg?

  • After the first 6 hours, what is the vinegar and egg looking like?

  • What does it look like after a full day?

  • Finally, what is the end result?

How To Separate Salt & Pepper


  • Table Salt

  • Pepper

  • Plate

  • Comb

  • Optional - inflated balloon or wool


  1. Sprinkle a good amount of salt and pepper to a plate. Mix together.

  2. Charge your comb with static electricity by running it through your hair, by rubbing it against a balloon, or rubbing it on a piece of wool.

  3. Slowly move your comb across the pile of salt and pepper. Watch your pepper lift from the salt and onto your comb!

Take Note

  • What happens when you charge the comb and hand it off to another person? Does this experiment still work?

  • Why do you think the pepper is separating from the salt?
