Our fantastic science fun this Friday

Today we learnt all about contraction and expansion. We did this experiment with an egg and a bottle and the egg went into the bottle. For this experiment we used: A glass milk bottle, hard boiled eggs, matches, newspaper, and a balloon. To start we lit the match and lit the newspaper and put the paper in the milk bottle.Then we put the egg over the top of the bottle. As the fire went out, the air in the bottle cooled down and then the egg slid into the bottle. We also did the same thing with a balloon. When the fire had gone out in the bottle, the air in the bottle cooled down and sucked the balloon inside the bottle. It was lots of fun.
