How to make a fiber optic light diffuser with a dot of hot glue

This is the method I use to make my glow-dot LED capes and flags. Materials needed: * fiber attached to an LED light source *hot glue gun *teflon or other non-stick work surface *cold metal spoon in a bowl of ice - the thicker the spoon, the better it will work Make sure your spoon is nice and cold first! You are using it as a heat-sink and it needs to be chilly. The non-stick work surface is key here. I ponied up for a 3’x4’ sheet of solid teflon, but you can make do with a large tempered-glass cutting board sprayed with PAM or some other kind of low-key silicone grease. I’ve even used solid shea butter in the past. When your glue gun is nice and hot, stick a dot of glue over the fiber, right on the work surface. The fiber is thermoplastic, so it will bend very easily in the glue - as you bend it, you can see that light is now diffusing out through the glue dot. Grab your cold spoon and freeze the glue dot! You can peel the dot
