Super-spreader
Despite the parachute structure of the individual Dandelion seeds being largely made up of empty space, it is believed their design creates a ring-shaped air bubble ("separated vortex ring") which slows their descent to the ground and allows them to spread further afield (and into my garden as an unfortunate consequence). It is thought their design is up to four times more efficient that a conventional parachute.
