So these girls are showing the other kids what their project is about, the topic for this term is Force and motion. Basically they have stuff on their table which does push or pull. The rainbow stuff are just popits, its only rubber which can pop and pop. Then the boy blowing the balloon is actually trying to get his party popper which he cuts the top of the balloon and put the balloon at the end of his toilet roll and pulls the thing where blow the balloon, but first you will need confetti to make it look like a actual party popper because its the main thing. Then when you pull the ballon then all the confetti pops up and make a mess.
