      Hi Faye,

      The lasers we use are actually invisible! They’re in the infrared part of the electromagnetic spectrum, rather than the visible part which we’re able to see with our eyes. This makes them more dangerous because if one hits you in the eye you don’t even realise it until the damage is done, because you can’t see it!
