Egg Science Experiments and Floating Egg Trick

One of my boys is really into magic right now. He came home with a fun floating egg science experiment that he’d learned at school.  And since I’m a sucker for science experiments and my husband was a science teacher we were quite excited that he was into his science lesson or magic trick (from his perspective).  Science experiments can sometimes seem like one awesome magic experiment, so it’s all good in our eyes!

My son’s science experiment had to do with density. Objects sink when their own density is greater than the liquid’s density. Density is the amount of matter contained in a given space or volume.  So in this case the egg is denser than the tap water therefore it sinks. Salt water is heavier than ordinary tap water therefore it’s capable of holding the egg up.

Looking for some fun educational activities to enjoy during your Easter break? Well, look no further!

Floating Egg Trick

What you need:

  • salt
  • water
  • 2 glasses
  1. Fill a glass with water half way.
  2. Place the egg inside the plain water and watch what happens.
  3. Add 3 teaspoons of salt to the other glass of water. Place egg inside it and watch it float. It took 3 teaspoons of stirred saltwater to get my egg to float. If you need more salt add another teaspoon.
