I recently rediscovered the magic of non-Newtonian fluids (cornstarch) that grow more viscous as they are disturbed. Maybe you’ve encountered this effect before as a science experiment. Cornstarch will run freely along the palm of your hand, but when once touched it it hardens and clumps together acting more gooey than the watery form it previously occupied. Left undisturbed for several seconds, it quickly retains its original liquid state.
But I never tried putting cornstarch on a vibrating speaker. Witness another kinda life:
