But then how do birds fly? We dropped two pieces of paper to the ground from the same height at the same time. One was scrunched up in a ball and the other was flat. The flat piece seemed to float down to the ground and took longer to get there. We decided that this was to do with the air catching in it, like birds’ wings or a parachute.
We made our own parachutes using a tissue, 4 pieces of thread, a piece of Lego and some sellotape. The air caught in the parachute and brought the Lego safely down to the ground!
