Maple seeds spin like tiny helicopters as they fall, slowing their descent and catching passing breezes.

The longer version

The winged fruit of a maple is shaped so that its weight sits on one side. As the seed falls, air pushes against the flat blade and the fruit begins to rotate, much as a rotor does once it starts moving.

That spinning slows the descent considerably, giving wind more time to carry the seed sideways. A stronger gust can lift it far from the parent tree, reducing competition for light and space. The wing also acts as a stabiliser, keeping the seed upright so it lands in a consistent position. The two seeds in each pair can separate in mid-air, giving each one its own path away from the tree.
