What Playing a Vinyl Record Looks Like Under a Microscope

This is what playing a vinyl LP looks like through a homemade electron microscope. Grooves that are relatively smooth to the naked eye suddenly become uneven, zig-zagging paths.

An electron microscope can see in much more detail than a light microscope (like the one you’d use in science class).

Ben Krasnow, host of the YouTube series Applied Science, demonstrates how he made the microscope images in the clip below. Warning: records were harmed in the making of this video.
