A
ray gun that can stop people in their tracks without harming them may sound like
science fiction, but some experts believe it could soon be reality.
The gun is designed to zap its victim with an
electric current, using a laser to carry the charge along a beam of
ultraviolet light.
The light particles, called
photons, would create a path of
ions through the air that will be capable of conducting
electricity up to a distance of about 100 metres (330 feet).
When the current hits someone, it would interfere with the tiny electrical charges that control the victim's muscles, making movement
impossible.
But
vital organs like the heart and diaphram would not be affected because they are protected by a greater thickness of body tissue.
