Floating egg experiment

What you need:

• egg in its shell (it can be boiled or raw)
• an almost full glass of water
• 1 tsp of salt

Number of players:
1+

Activity:

Carefully place the egg into the glass of water.

Initially the egg will sink to the bottom.

Pour in two teaspoons of salt and stir carefully around the egg.

Continue to add the salt and stir until the egg rises.

Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water.
