An egg is placed on a glass of three quarters full of water.The force of the weight make the egg sink at the bottom of the glass.Salt is put to the glass and stir.The egg no longer is sinked but actually floats.The density of the water is increased with the salt and is created a buoyancy force,acts upwards.
1. Fill the glass three quarters full of water.
2. Put the egg into the water, it should sink (if it doesn’t grab a different egg).
3. Now put in salt and stir.
4. Keep putting in salt and stirring until the egg no longer sinks but actually
floats.
5. If you’re lucky, you may reach a point where the egg neither sinks nor
floats but hangs in the middle.
