What you need
- Raw egg
- Large pop bottle
- Sticky tape
- Cut the top off the bottle and put the egg inside
- Fill the bottle with enough water so that the egg is well covered. Add salt to the water, stirring, until the egg floats
- Tape the top of the bottle back on. Drop the bottle to the floor from waist height
Results and Explanation
The egg doesn’t break because the salt water spreads the impact across the whole egg. Try dropping the egg in the bottle without the salt water.
