What is dust made of? - Michael Marder (2018x50)

:

Less than a tenth the size of an ant, a dust mite’s whole world is contained in the dusty film under a bed or in a forgotten corner. This realm is right under our noses, but from our perspective, the tiny specks of brilliant color blend together into a nondescript grey. What are these colorful microscopic particles? Michael Marder explores the science of dust. Lesson by Michael Marder, animation by Mette Ilene Holmriis.
