International Year of Chemistry: no fire for a fried egg

MATERIALS:
- An egg.
- A plate or a bowl.
- Alcohol.
INSTRUCTIONS:
- Break the egg and put it in the plate.
- Pour some alcohol on it.
- Wait half an hour.
- It's a fried egg!
WHY?
Eggs contain proteins. When you heat proteins they undergo a structural change called denaturation. You can get the same result with alcohol. In this process the egg white becomes solid and white.

    No fire for fried egg needs no fire. You put alcohol on the egg in the plate and the egg is a fried egg.
