The Amazing Harold Edgerton (1903 -1990)
Harold Edgerton's story is one of humble Nebraskan beginnings that sparked a child's curiosity for taking things apart to see how they worked. So bloomed the genius that led him to become an MIT Professor who founded his Strobe Alley workshop which perfected stroboscopic photography. His amazing works include a lightbulb stopped in the process of shattering, the drop of milk frozen in midair splash, a bullet shown shooting it's way through a playing card, shredding it in half as it goes. One of the things Edgerton was asked to photograph was the night time detonation of an atomic bomb by the military. He managed to capture the process beautifully but also the strange beauty of destruction at the same time.

Edgerton built a special lens 10 feet long for his camera which was set up in a bunker 7 miles from the source of the blast which was triggered Nevada - the bomb placed atop a steel gantry anchored to the desert floor by guide wires. The exposures are at 1/100,000,000ths of a second.

In a millisecond the blast expands; lightning caused by the force of the energy travels down the guide wires The desert floor was turned to glass

In another millionth of a second, a planet of fire exists,
silhouetting and dwarfing the Joshua Trees

How do they setup the camera to actually take the picture upon detonation? Its obviously impossible to have a human with a button...

I believe it's like a "Gatling Gun" constantly taking photo frames...starting seconds before the detonation, until seconds after burning through all available film.....but it must still be hard managing the time "window".

It will be cool to see if digital imagery takes this to another level since the only limitations would be digital optics/shutter speed and electronic storage capacity.

Well couldnt you just hold down the button no?

I did the same thing but on a smaller scale... I put a marshmellow in the microwave and put it on high.. right at the 30 second mark it exploded and looked like the picture above.. what's hilarious is that when you turn it off it suddenly deflates into a pile of mush.

Did you know that if you put a raw egg (in its shell) in a microwave, it will detonate with enough force to blow the door off the microwave?

Someone I know didn't believe this story. The next day, she and her roommate were at Target shopping for a new microwave :)

Did you know if you put bugs in the microwave it is entertaining... if you get bored that is...

Try putting a compact disc into the microwave. It wont damage the microwave but it will destroy the Cd with extremely entertaining rresults.
