Bill describes how the minimization of surface area and inertia compete to form droplets. He then shows how engineers use this knowledge to create precisely-sized droplets in a commercial inkjet printer -- the type used to print expiration dates on food packages.

This channel is really underrated and I've Heard your making a new series, I'm really looking forward to it.
Do you have any secondary media like twitter (or even the yt community post thing) where you can keep us updated. Best of luck on your new project

Fantastic Video engineerguy. Thank you. Quick question - "the surface area to volume ratio of a sphere is double that of an optimised cylinder with the same radius - should it not be volume to surface area ratio? i.e. more volume per surface area, not more surface area per volume?

I absolutely love how clear and concise you are, with keeping things simple for the sake of brevity. Awesome stuff!!
