Glow-in-the-dark Octopus

Jason made this glow-in-the-dark octopus figurine out of InstaMorph moldable plastic and Gluminous glow-in-the-dark powders. He used sky-blue and pink for the octopus body and green pigment powder for the kelp behind it. In these pictures, it’s sitting on a bed of sand with a UV lamp pointed at it in various angles.

You can see in the picture of it under normal light that the powder, once mixed in with a medium, is mostly white/unnoticeable. When fully charged or hit with a UV light source directly, it glows a brilliant blue and pink!

Jason was able to do this by mixing in a small amount of powder into the moldable plastic while it was in it’s malleable state. By “kneading” the pigment evenly into the plastic, he was basically able to make his own glow-in-the-dark plastic. How cool is that?!

When working with moldable plastic, we recommend you start with a small amount of plastic and pigment and fully distribute the color before molding. Also, be careful when using hot water to heat up your plastic. Water can deactivate some of the Gluminous glow-in-the-dark powders so they won’t glow as well, so try to remove as much water as possible before integrating the pigment powders.
