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.
