We have been learning about forces with my maths group the ovals.
First we did a balloon experiment. We first attached a piece of string to two chairs and then we put a straw on. Then we taped a balloon to the straw then we blew up the balloon and let go it went down the string. This is because of the air force of the air trying to get out which pushes the balloon.
