This clip is about microscopes and its development. It begins with a CU of a flea. Cuts to a shot of an early microscope. A CU of the microscope. A CU of the eye piece of a microscope. A blurry shot of bacteria. A shot of a microscope made entirely out of silver for King George the third. A shot of an image being distorted through curved glass. A shot of melting a rod of glass to make a lens. A shot of light passing through a prism.
