SLJ - Ultraviolet

 Last year I made a UV bracelet so I just hung it up outside. UV bracelets have beads that change colour if there are UV rays.

    I can't remember how exactly I made it, but there was a special knot you had to do that looked like a four. I don't know if you can buy the beads at a shop but I think you can (I was given the beads). The beads are different colours and when there's high UV they turn bright blue, pink, and yellow. On the day I took the photo they were so pale they were almost clear.
