How to mould glow in the dark pebbles.

This project was inspired by a small pack of glow in the dark pebbles I added to an ebay order. They are made of plastic with a very small amount of the photoluminescent pigment and don't glow very brightly at all. We can do better than that, since we can cast our own with two part resin and as much pigment as we like. This video shows the making of the moulds, mixing and pouring of the resin, and the demoulding and testing of the finished shapes. You can find the photoluminescent powder on ebay. there are two types, the older dimmer one and the new rare earth type that glows brighter for longer. The key words on ebay are Strontium Aluminate.
