Getting a hard boiled egg into a bottle

This was an experiment I saw online a few years back, and I've always wanted to try it.

Q: How can you get an egg to fit into a bottle with an opening smaller than the egg?
A: Science!  Check it out!

Materials:

• Open mouth bottle - large enough for an egg to squeeze through it, but small enough to seal the top with an egg.  ***Please do not use a container that once held alcohol!***
• Matches (for adult use only)
• 1 peeled hard boiled egg*

Methods:

• Light a match (or 3 in our case).
• Carefully place match(es) into bottle.
• Cover the top with a hard boiled egg.
• Watch and note what happens

Notes:

• We used a 32 oz Gatorade bottle (note J's red juice mustache).
• We used rice as a "padding" for the fire since I was afraid that plastic burns.
• We didn't show it, but one match didn't heat up the bottle enough to do anything.  3 matches worked well.

Results:

• We had so much fun, J wanted to do it again! Queue video 2:

Discussion:

• The fire from matches heats up the bottle, and having the egg on top of the bottle helps extinguish the fire.
• As the bottle cools, the air contracts, pulling the egg into the bottle.
• The trick then becomes seeing if you can get the egg back out.  We cut it up to get it out and properly recycled the bottle.
• My favorite part of the experiment was the surprise when the egg got sucked in completely.  POP!

*edited to add this note: hard boiled eggs peel better when they are a few days old (something I didn't know since I don't eat eggs).
