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.
You need:
A tall glass
Water
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.
I love those dancing raisins - we might have to do this after school today! Very clever with the egg. I thought it might have had something to do with the egg being cooked, but I was wrong! Does this mean an egg will float in the sea (which is saltly water, but might not be as salty as in your experiment). Great learning!
