Egg in a Bottle

Insert an  Egg to a Bottle

Learn about the relation of temperature and pressure as you watch an egg get sucked into a bottle.This project requires adult supervision.

What You Need

Egg 

Saucepan and stove 

Wide-mouth glass drink bottle (such as a Starbucks Frappuccino bottle-the mouth needs to be a little smaller than the egg.We used  a large egg with the Starbucks bottle,but with other bottles you might need smaller eggs.)

Matches 

Strips of paper folded a couple times length-wise (slightly shorter than the bottle.)

What You Do                 

                    

1.Place the egg in a saucepan and add enough water so that the eggs are covered by about an inch.Let the water boil for 5 minutes,then remove the pan from the heat and cover it.Let it sit for 25 minutes ,then remove the eggs and dip them in cold water.

2.Use a paper towel to coat the inside edge of the bottle mouth with a little bit of vegetable oil for lubrication.

3.Peel one of the eggs,then dip it in water and set it with the small end down in the mouth of the glass bottle.It slightly larger than the mouth of the bottle ,so it does not fit inside.

4.Use a match to light the end of a strip of paper on fire.Lift the egg off the bottle ,drop the paper inside with the flame down,and quickly replace the egg wiggle a little in the bottle mouth,and then get sucked inside!
