miXscope - Snapshot of the Week

Why doesn't the filament in an incandescent light bulb burn up?

The microscope was handheld and the small 4 watt
incandescent light bulb was turned on and then off.

The microscope's auto exposure was turned off
and an image overlay is in the bottom right corner.

A small hole was put into the base of the light bulb.

The movie was captured with a Smithsonian
Computer Microscope at 10X magnification.

Use the left and right movie controller arrows to
step through the movie one frame at a time.
