We made our first toys today that needed air and a pushing force to make them move. We learnt that when we used a pushing force to throw them in the air, the air pushed up under the blades to make them spin. It was very exciting but it was our first try.
We soon discovered that they dropped down to the ground very quickly before they started to spin. We also found that the thin card we used didn't last very long!
So, back to the drawing board to see if we can design another one that might last longer next time.
