If you′re into science and stuff, that channel is a gold mine. The guy literally build an scanning electron microscope (SEM) and a mass spectrometer (out of other stuff) in his garage, with some Home Depot and Ebay parts.

The video is from a commercial SEM he acquired later on, but still it′s really nice.
