Fire, oxygen and an egg

Yesterday we did a science experiment with fire, oxygen, and a hard boiled egg.

Burning uses up oxygen causing a vacuum. Since there is more air pressure outside of the bottle, the egg gets pulled into the jar.

Our jar was too small. It didn't hold enough oxygen to burn the candle long enough to completely pull the egg in. For best results use a glass milk bottle.
