Try “Pocket Experiments” from Albi and make your own glowing slime. After being exposed to light, the material “charges” and can then emit some of the stored light – that’s exactly how photoluminescence works.
Everything you need is included in the package, and you’ll mix the slime directly in the test tube. The set is designed to be simple, playful, and fun for children aged 8+.
The price is for 1 package (1 set).
