Here's some fun for the kids (and big kids too). Try shining this UV black light torch and see how many items you can find that will change colour. Use as a great accessory in the classroom Bead Shack has 2 ranges of beads that change: Click here for our amazing UV Beads which change from white to coloured, then back to white when the light (or sun) is taken away. The ultraviolet beads will cycle back and forth (to bright colors and back again) over 50,000 times! Use these beads to control how much sun the children are exposed to (full information in the listing for UV Beads). Click here for our "Vaseline" glass vintage Czech beads which include a small amount of uranium in the glass, which glows under the black light torch. See the photos of those listings of amazing products (mostly vintage) that glow in the dark!
