Korean designer Wonsik Chae's light concept is in the shape of a teabag filled with fluorescent molecules that react to chemicals in a teacup. The result: a new meaning to the words "tea light."
Much like normal cups of tea, you dip the teabag in to start the reaction. You then "draw a light" by pulling up the teabag and letting the fluorescent molecules slip into the chemical concoction. Draw it multiple times to make the concoction darker and thus the light brighter.
While it's bound to make your party prettier, it seems like something you should warn your guests of beforehand. Something tells me this tea isn't drinkable. [Toxel]
