A Magic Egg
Fresh eggs will sink if dropped into water, but this egg is suspended in the middle of this glass - how is that possible?
The magic word is density.
A tall glass
6 tablespoons of salt.
- Mix the salt with half a glass of water - give it 10 min to dissolve.
- Carefully pour fresh water into the glass - holding the glass on an angle helps to stop the fresh and salt waters mixing.
- Gently drop the egg into the glass.
