An egg-cellent trick

What you'll need:
* an egg
* matches
* a glass bottle

* Hard-boil and peel an egg; set aside.

* Drop two lit matches inside a glass bottle with a long, narrow neck and an opening just wide enough to keep the egg from falling in (we used a milk bottle).

* Have your child set the egg on top of the bottle's mouth while the matches are still lit.

* Watch the egg get sucked down into the container.

How it works: After the matches burn out, the air inside the bottle cools, lowering the pressure there. Now, the air pressure outside the bottle is greater, pushing the egg inside.
