The Scientists in Science Club tonight learnt about forces. The children each created a cone shape which they shaped into a mouse. They then placed their mouse on top of a plastic bottle.
The children found that when they squashed their plastic bottles, the air inside was pushed out through the top and the force created sent the rocket mice flying into the air.
The children had different sized bottles and discovered that the harder they bashed their bottle, the stronger the force of escaping air and the higher the mouse rocketed.
