A portable foot shower designed by an 11-year-old from St Albans has won the Science Museum's summer invention competition.
Sophia Laycock's 'Pediclean' washes the sand off your feet when you've been on the beach.
She beat over 60 entries to win a 3D printer worth £2,000.
The device consists of a plastic bottle which attaches to a pipe and when squeezed, dispenses a spray of water onto the feet which are placed on a platform.
It's designed to be light-weight and easy to transport while on holiday.
Sophia said: "I'm really thrilled to win this competition. I've seen foot showers at beaches whilst on holiday, but never seen anything like that in Britain. The 'Pediclean' is just a simple way of cleaning sand off your feet so the sand stays at the beach and doesn't get in the car!"
Mark Champkins, Science Museum Inventor in Residence said: "This product is an ingenious solution to one of the most irritating problems experienced on a trip to the beach." The 'Pediclean' is a smart and simple design that I can imagine in the shops."
