Slime. It’s never around when you need it.
So it’s a good job that I managed to find a good little tutorial on Youtube that teaches you how to make your own, safe, atomic, UV reactive slime.
All you need is some PVA, borax and some dye (preferably glow in the dark stuff).
The instructions are simple and the stuff looks great fun! Plus, the site that made the video are keen to get us all to appreciate the ‘science’ side of it too, so it’s slime that teaches you stuff!
