A collaboration between Bill Pechet and Chris Pekar, this 35-foot-tall, 31-foot-wide flask graces the entrance of the Millennium Library in Canada.
What makes this huge flask sculpture amazing is that it changes color, as though chemicals are bubbling within.
Pekar, who is the mind behind the lighting, has placed 28 LED lights on a H-beam, with half of them illuminating the water and the other half lighting up the fog.
The color changing sequences also accompany the seasons—there are 18 of them for summer and 9 for winter.
