Egg in a Bottle

Question: Can we get a hard boiled egg in a glass bottle with a smaller circumference than the egg?

Hypothesis:

Yes, we believe the egg will fall into the bottle due to the change in air temperature and air pressure . The pressure of the air outside the bottle is so great that it literally pushes the egg into the bottle.  This is a great way in seeing how powerful air pressure can be, you will be amazed.

Our Experiment

Materials: 

Picture
1 Hard Boiled egg, Peeled
1 Glass Bottled with the mouth smaller than the egg
 1 Book of Matches
                    Vinegar
Baking Soda

Safety Procedures


Matches: Be careful, strike correctly

Procedure:

  1. Cut a strip of paper and carefully use a match to light the strip of paper at one end and drop into the bottle.
  2. While the strip of paper is still burning in the bottle, place an egg on the mouth of the bottle.
  3. With the egg sitting on top of the bottle, the burning strip of paper extinguishes itself.
  4. The hardboiled egg slowly squeezes through the top of the bottle and drops to the bottom.

To get the egg out of the bottle:
  1. Place Vinegar in the Bottle
  2. Place Baking Soda
  3. Turn Bottle Upside Down
  4. Watch slowly as the egg slides 







Special Needs:
Fire extinguisher in case of fire.


The Science behind it

The burning piece of paper heats the air in the bottle and causes the molecules to move far away from each other. Some of the heated molecules actually escape out past the egg that is resting on the mouth of the bottle. When the flame goes out, the molecules of air in the bottle cool down and move closer together.  The pressure of the air molecules outside the bottle is so great that it literally pushes the egg into the bottle.




Conclusions

The effects of variations in air pressure are clearly demonstrated here. By dropping a burning match into the bottle just before placing the boiled egg on top of bottle, the flame burns up all the oxygen inside the bottle. This in turn creates a vacuum inside the bottle that sucks the egg into the bottle.
