How to Perform the Egg Into a Bottle Experiment

Watch as an egg is sucked into a bottle.

Teach children about the effects of air pressure with an experiment using an egg and a bottle. Changing the temperature of the air inside the bottle results in a change in air pressure. The effect on the egg will amaze young audiences.

Things You'll Need

• Glass bottle with a mouth slightly smaller than an egg
• Hardboiled egg
• Matches
• Small piece of paper

Instructions

1. Peel the hardboiled egg and pat it dry with a paper towel.

2. Roll up a piece of paper about 3 inches square. Twist the paper until it is tightly wound.

3. With the bottle in an upright position, light the piece of paper and drop it into the bottle.

4. Place the peeled hardboiled egg onto the mouth of the bottle, pointed side down.

5. The egg may begin to jiggle around a bit. Once the fire goes out because the oxygen supply is cut off, the egg will quickly be sucked through the mouth of the bottle.

Tips & Warnings

• Use a dry empty bottle that does not contain any flammable residue inside.

• Most of the time the egg will be intact once it's been sucked in, but results may vary.

• Do not attempt this activity without adult supervision.
