What You Need:

• One egg
• Glass half filled with water
• 1/2 cup salt

Instructions:

1. Put the egg in the glass of water and notice that it sinks to the bottom.
2. How can you make the egg lighten its load and float to the top? Here’s how to do it.
3. Pour the salt into the glass and stir.
4. As the salt dissolves, the density of the water thickens which makes the egg float!

A nice little demonstration about density.
