In this Goobertown Hobbies video, Brent delves into some hobby science with his new digital microscope to look at a bunch of synthetic and natural bristle paint brushes, from the very cheap to the expensive.
The results are fascinating. Under the microscope you can really see why natural bristle brushes are superior to synthetics. One of my favorite parts of the video was seeing his dirty old brushes under the scope before and after a thorough cleaning.
