Secret of Dandelion Flight Discovered by Scientists

Fluffy dandelion seeds are known to travel 500 miles on the wind, but until now it has been a mystery how they did it. Although light enough to be whisked into the air in updrafts, their downy heads are 90 per cent empty space - a poor design for a parachute - and scientists have puzzled as to how they manage to stay afloat for so long. Now researchers at Edinburgh University have discovered that the soft bristles work together to create a ring-shaped bubble of air which keeps the seed aloft.
