Winged helicopter seeds falling from a Maple tree. 🚁

What appears to be a tiny toy helicopter is actually a highly efficient method for planting a forest. These are maple seeds, called samaras. Their light, wing-shaped structure and slight tilt cause them to spin as they fall, much like a helicopter rotor. This autorotation slows the descent, lets the wind carry them and allows the seed to land much farther from the parent tree than if it simply dropped straight down.
