Martin Butson has helped invent a small sticker that indicates when water has been purified through UV exposure

The stickers can be placed on a reusable plastic bottle and change colour when the water is safe to drink

The stickers have been used in a pilot program in Cambodia that has already helped thousands of people

The SAFE sticker is a UV purification label that works by simply sticking it on a bottle of contaminated water, putting the container in the sun and waiting for the UV light to kill harmful bacteria, viruses and microorganisms.
