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|
- 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.
Why does this happen?
