The Paper Helicopter Experiment

Cut along the SOLID lines. Fold along the DASHED lines. Fold flaps C and D inward, then fold the bottom up; this will create a handle of sorts. you can also make your own design like Grace did. Let us know in the comments below how long it took your helicopter to go down.

 

EXPLANATION
As a result, there is less air pressure on top of the wing; this causes suction and makes the wing move up. A helicopter’s rotor blades are wings and create lift. An airplane must fly fast to move enough air over its wings to provide lift. A helicopter moves air over its rotor by spinning its blades.

 

Why does it spin? (Because of the wing shape and the pressure of the air as it falls.) They kinda fall like maple seeds.
