"This is a 3D environmental project I completed during the summer of 2012 at the University of Florida. The idea was to introduce a subtle but fun element into the environment that people could enjoy. I placed them around campus on the final day of classes."
This bulbous, ethereal shape is a spreading flame front captured by artist Fabian Oefner in his new "Aurora" series. Oefner used a few alcohol droplets in a glass vessel and ignited the volatile vapors, capturing the propagating flame. Take a look at it in action. Because the air inside the vessel is mostly still, the chemical reactions in the combustion occur much faster than the air’s motion. As a result, the flame spreads as a thin sheet instead of a uniform, widespread flame. The wrinkled and corrugated look of the flame front is due local turbulence distorting the flame.
