If you've ever bitten into a Wint-O-Green Life Saver candy in the dark, you've probably noticed an accompanying spark of light. Marshall Brain explains the chemistry behind the phenomenon known as triboluminescence in this episode.

Lots of creatures are able to glow, like fish, mushrooms, fireflies and even some bacteria! This special ability is called bioluminescence and it looks like magic, but it’s actually chemistry. In this episode, we’ll travel to the bottom of the ocean in the ExPLORERR to meet some ...  Show more
