PUERTO RICO: Bioluminescence is a natural phenomenon where “living organisms emit light”, oftentimes when disturbed. You have probably seen this on land–fireflies lighting up the night–but it can also occur in the water. Mosquito Bay in Vieques Puerto Rico is the brightest glowing bioluminescent bay in the world.
In class, we dyed different cups of water with fluorescent highlighter ink (pink, yellow, green, blue), and then watched as the colors glowed brilliantly under a black light. Classes also saw their socks & shoes light up, and then tried scribbling on their hands with highlighters to produce an effect very similar to bioluminescence. Note: This made my hands itchy, so be sure to wash up immediately afterwards.
HERE is a list of a few more glow-in-the-dark projects to try at home. $1 glow-in-the-dark paints &/or glow sticks are always a great investment. There are Bioluminescent Kayaking Tours available in some parts of the country to see it in real life as well.
