How are dandelion seeds able to travel distances of over 150km across oceans, with only small feathery bristles and the power of the wind? According to research by Cathal Cummins at the University of Edinburgh, the answer can be found in the fluid dynamics of the air flow around the plants ‘micro-parachute’, and in the future it could lead to improved flight for miniaturised vehicles such as drones.
