First you need to gather up all of the materials you will need.  Below is a list of the following items needed to conduct this experiment:

  • A hard-boiled egg
  • A clear long neck bottle
  • 3 matches
  • Adult help/supervision

Are you ready?  Let’s get started.  First you’ll need to hard boil the egg.  Let the egg cool and then peel the shell off of it.  Next, grab your bottle and your adult.  Take the 3 matches and light them all at the same time and drop them in the bottom of the bottle.  When the flames go out, place the egg gently on top of the bottle (at the mouth).  Observe what happens next.

By burning the air inside the bottle, it also decreases the pressure inside the bottle causing the egg to decrease in size.  Eggs are not solids.  They have air pockets in them sort of like sponges do.  When the egg decreases in size it becomes a solid, which in turn, allows it to slide through the opening of the bottle.

    Egg does not shrink actually, rather it goes inside because burning matches cause oxygen depleted n creates a vacuum which sucks egg inside
