exploding light bulb
High-speed photography: A light bulb was shot with an airsoft pistol (positioned right of the lamp). The camera was triggered by a photocell, which was located in front of the pistol muzzle. Because of the low energy of the projectile, the bulb burst and only few fragments were swept away. This gives the impression that the bulb is exploding. The scenery was “frozen” with flash lamps which had flash durations of 1/6000-1/8000 seconds (depending on their power). The threaded base on the bulb was added later by digital photo editing, because having the bulb screwed into a lamp socket (see other versions below) made the image less impressive.
