Imagine having a lamp that requires no energy and turns off on its own. Also imagine having a pet that won't die without your constant supervision. These come together in the bioluminescent hourglass!
Bioluminescence is the ability of organisms to emit light, and has independently evolved in several different species. In the Bioluminescence Community Project
, we've been working with a number of bioluminescent organisms, including tiny, single-celled creatures called dinoflagellates
that live in the ocean are responsible for the phenomenon of glowing waves
Dinoflagellates are a type of algae that will light up at night when they are being perturbed. Here, we give them a nice gentle stimulation to get them to glow, by running them through an hourglass
You can order dinoflagellates online at one of the links listed here
