Germans invent tricycle powered by screwdrivers

Graduates in Germany have invented a tricycle powered solely by screwdrivers.

The EX, made with two portable 18V Bosch electric screwdrivers, was inspired by a skeleton holding in its organs, say Sebastian Auray, Nils Ferber, Ruben Faber and Ludolf von Oldershausen who studied at the University of Fine Arts Hamburg.
