3Next sketch a thick letter T onto the paper and cut out the T.
4Snip the middle of T at the top.
5Fold the right side in one direction and the left side in the other direction.
6Raise those flaps up gently so it looks like a helicopter.
7Fold the bottom part of the T up about 1 centimeter and attach the paper clip.
8Carefully drop it from a high place and watch it twirl.
How It Works
The weight of the paper clip pulls the maple seed model down toward the ground due to gravity. Due to its shape, the moving air pushes up on the blades and causes it to spin around. This is similar to the shape of helicopter blades. Maple seeds glide down slowly and can be carried by wind to land far from the tree it grew on.

Pollen needs to be moved from one flower to another.
