On the streets of London a helmet can save a cyclist's life.

Anirudha Surabhi knows this only too well. He was in a bike crash in 2009.

He had a lucky escape but his polystyrene helmet was destroyed.

Now he's come up with what he says is a safer model, which was inspired by the woodpecker.

His paper helmet is designed in a similar way to the bird's head and beak and offers protection by cushioning the cyclist's head.
