3D3DGiant flash bulb.
This is a huge zirconium wool flash bulb. It's as big as a regular household incandescent bulb, which is much bigger than any flash bulb I've seen. Must have been pretty darn bright. Not to mention expensive in its day, when you consider that each one could only be used once. Imaging that: It used to actually cost money each time you took a photo! Money for film, money for developing the film, and if you needed flash, more money for each flash. Now we take 720 photographs of every sample (a complete circle in 1/2 degree increments), each of those photos is higher quality than an old 35mm film photo, and it doesn't cost a penny more for each one, beyond wear and tear on the camera and a bit of electricity.
