Hong Kong company Wicked Lasers has manufactured âÅ"the most dangerous laser ever created,âÂ a lightsaber with a blue beam that can burn retinas and set skin on fire.
The Spyder III Pro Arctic features a 1 watt laser the company warns is the most powerful portable laser available. The beam is a thousand times more powerful than sunlight on skin and the manufacturer warns it could cause cancer.
