 Troubleshooting 

What should I do if my eggs are broken by the heat?

- Eggs want constantly rotating to avoid giving a certain part too much heat, which will damage the shell of the egg. You also can do this experiment with only an eggshell.
 

 Question to Ask 

  1. Why does the egg turn black?
  2. What is the silver covering around the egg in the water?
  3. Remove the eggs from the water, will the silver covering still exist?

 Scientific Description 

The candle blackens the egg. The soot produced by Incomplete combustion of the candle is attached to the eggshell. The root covering made of carbon is loose, and it absorbs a lot of air. The soot re­pels the water and coverings the egg with a thin layer of air, which reflects light, thus making the egg look silver.

 Extensions 

  1. You can replace the egg with an eggshell.
  2. You can try to make a suspended silver egg. Suspended egg
