What You Need:
- OneÂ egg
- Glass half filled with water
- 1/2 cup salt
- Put the egg in the glass of water and notice that it sinks to the bottom.
- How can you make the egg lighten its load and float to the top? Here’s how to do it.
- Pour the salt into the glass and stir.
- As the salt dissolves, the density of the water thickens which makes the egg float!
