1st place winner in the Wikimedia Commons Picture of the Year 2013 Contest. The photo description states, “The glass bulb of the lightbulb has been opened, causing the inert gas inside to escape. When turned on, the tungsten filament burns with a flame, due to oxygen entering the light bulb. The light bulb was screwed into a socket, which was replaced with the lamp base using image processing.” Photo #1 by Stefan Krause, Germany
