When I want to make glow in the dark resin toys I use a clear resin from Smooth-On.com called Smooth Cast 325. I order Glow Powder from GlowInc.com – they have several types, but I get the top of the line $250/pound Ultra Green Glow Powder. It’s the brightest glow powder on earth. These resin toys glow for 24 hours after being in sun light. I’ve never seen any toy glow like this. You could use a lot less glow powder, but I like the toys to glow like a light bulb. Check out my How To Make Resin Toys book for step by step details on how to make resin toys.
