The Origins of Worms
Worms glow blue under UV light when they're dying. Researchers found the source of the blue was actually a molecule called anthronelic acid, which is found in the worms guts. Another way to make a worm glow blue is to threaten a marine parchment tube worm so that it makes its patented glowing blue mucus for several days.
From trustworthy to calming, sad to steadfast, and, of course, jeans - the color blue means a lot of things to a lot of people. Join Team Tangents as we delve into this deceptively complicated primary color!
