Radio head ... straw hat has receiver built in
FROM a radio in a hat to a one-wheeled motorbike, these are wacky 1930s inventions that would have left the Dragons’ Den panel bankrupt.
None of the bizarre creations — which have emerged from Holland’s science ministry — ever caught on.

Kid lid ... a pram to withstand gas attacks
Sheet music ... a piano designed to be played in bed
Round trip ... a one-wheeled bike
Buoy, it’s daft ... amphibious bike
