What did students do?

Students lit a match, dropped that into the bottle and quickly placed the eggs on top of the bottle. Within few seconds egg which was bigger than the bottle opening dropped into the bottle.

What did they learn?

This mind blowing egg experiment was all about pressure. When they dropped the match into the bottle, the air heated up and expanded which caused some air to escape from the bottle. When the bottle cooled, the air inside contracted. The egg on the bottle mouth was forced into the bottle.

How did the activity go?

They repeated the experiment with a successful result.
