Did you know that the Chain Catshark exhibits a phenomenon called biofluorescence? Not to be confused with bioluminescence - these sharks don't actually glow in the dark nor produce their own light. Biofluorescence is where small, special molecules in the shark's skin absorbs the blue light of the ocean and emits it back as a glowing green light. We humans can only see this green glow using the help of UV lights.
How to charge a glow in the dark sticker?
Place your sticker in bright light to charge so the photoluminescent molecules in the vinyl material can absorb light energy.
