The helicopters have two seeds each inside them
Maple tree seeds are edible
The wings rough texture provides beneficial turbulence
Maple seeds do not fall off the tree until the wings are quite dry
Maple seed wings have many veins in them
The flat, elongated pods are densest at their seed-containing ends, a configuration that causes them to rotate while falling.

*maple tree sees are edible
*the helicopters have 2 seeds each inside them
*the wings rough texture produces beneficial turbulence and the weight of the veins improves the angle of the attack of the wing.

Maple seed wings have many veins in them
A new study has found that the aerodynamics that keep these seeds aloft also allow certain insects, bats and hummingbirds to hover.
Because the seeds descend slowly as they swirl, they can be carried aloft by the wind and dispersed over great distances
The leading edge of the vortex lowers the air pressure over the upper surface of the maple seed, effectively sucking the wing upward to oppose gravity.
