Easter Egg Science Experiment

I thought we’d do an Easter Science Activity.


Read on to find out what we did!

This experiment is to show that depending on whether we use tap water or salt water the egg would float or sink.

What you need:

  • Two glasses
  • Two eggs
  • Salt


  1. In one glass add plain tap water.
  2. In the second glass add salt and tap water mixing it well. I thought about 2 teaspoons of salt would be enough. I was wrong!! I needed to add a little bit more than 6 teaspoons!
  3. Now drop the first egg into the cup of plain water and point out that the egg sinks.
  4. Drop the second egg into the glass of salt water and notice that the egg floats!

I also gave Junior a small introduction to the the Dead Sea.

The Science Behind it: Salt water is denser than ordinary tap water, the denser the liquid the easier it is for an object to float in it.
