We all know that an egg sinks to the bottom if you drop it into a glass of ordinary water. This is actually a test for rotten eggs - they float.
But, how do you make any egg float in water? The results are very interesting and can teach you some fun facts about Physics.
What we need:
![]() |
One Raw Egg |
Lots of Salt |
Method:
- Pour water into the glass until it is about half full.
- Stir in lots of salt (about 6 tablespoons).
- Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
- Gently lower the egg into the water and watch what happens.
Observation:
If we were careful when we added the tap water to the salt water we will see the egg to amazingly float in the middle of the glass.
