Brussels sprouts battery to light up Christmas tree

A battery made entirely of Brussels sprouts is being used to light an eight foot Christmas tree in central London.

The battery was created by a team of scientists and engineers from The Big Bang UK Young Scientists and Engineers Fair and is being used to light up part of London's Southbank.

It was created using five power cells, each holding 200 sprouts, producing 63 volts from the 1,000 Brussels sprouts.
