J-Stace The Science Ace Separates The Egg Whites From The Egg Yolks

Join Jonathan every day at 9:20am on QC Morning for a new science lesson!

Hey parents! Looking for a substitute for your “science class”?

We recommend J-Stace the Science Ace

Separation can sometimes be difficult, but J. Stace the Science Ace definitely made it look eggstremely easy!

Learn how to separate Egg Whites & Egg Yolks

Ingredients and Supplies:

  • One egg
  • Empty plastic bottle
  • Bowl


  1. Crack your egg into one bowl.
  2. Gently squeeze the empty water bottle and put the opening on the yolk.
  3. Slowly release the bottle so it suctions the yolk out.


The Science Behind the Experiment
When you squeeze the bottle, you are decreasing the air inside. If you squeeze the bottle while the mouth is facing towards you, you’ll feel air rush out. Releasing the squeeze on the bottle allows air to rush back into the bottle. If you cover the mouth of the bottle with the egg yolk prior to releasing the squeeze, the available volume inside the bottle is filled by the egg yolk. The egg yolk separates easily from the egg white because of their differing viscosity.
Today’s vocabulary word is: Viscosity – resistance of a fluid to flow or a change in shape
