COLUMBUS, Ohio (WCMH) — NBC4’s Monica Day headed out to COSI to learn about a new exhibit that is open now.

‘Creatures of Light: Nature’s Bioluminescence’ brings about answers to many questions about fish and deep-sea ocean creatures that use light to survive. In the experiment that you can watch above, we learn about the chemicals that can make fish light up in the darkness.
