This video discusses two behaviors of drops of liquid. One is that that drops of liquid under a vacuum do not splash. Another is that drops of liquid with a charge do not splash.
We live in a world where we've been told since children that space is the final frontier; Here we can see that drops of liquid, something we live around every single day, has attributes that have only been discovered and documented in the past 20 years. The vacuum thing was documented in 2005, and the electricity thing was documented this year. There are no final frontiers we've discovered yet. Even the mundane in our lives have undiscovered properties.
Some people want everyone to think the world has nothing left to teach us, that there's nothing left to learn, that we know everything. It's a lie. There's everything left to discover, everything left to learn, everything left to explore.

@sj_zero Something semi-related: take a filter (cleaning the filter for a french press is how I discovered this) and run it under a tap. The water going into the tap will be turbulent and have bubbles in it (that's part of what the tap does, aerate the water) but the stream coming out of the tap will be laminar and bubble-free. The filter filters out the bubbles.
Which is the opposite of what you'd expect, right? You'd expect laminar + filter to equal turbulent.
@sj_zero Turns out this is a well known thing in the oil industry (mud going down a drillpipe is turbulent, the nozzles on the drillbit act like a filter, the same mud coming back up the annulus is laminar) but no one I talked to, petroleum engineers who knew this and designed things for it, could tell me _why_.
