P1/2 at Techfest

We are having our snack before the show. We went to a show called The ball that wanted to float. We found out that things that have air inside them would float. Things that are dense like the snooker ball sank. We learned a big word – buoyancy. We are squashed up tightly. We are dense like the snooker ball so we would sink.
We pretended to have air pumped in between us. We were not dense anymore. We could float if we were a ball because now we had air inside.
