  • I kinda want to do this for a "Graffiti Approved Area" where you let folks tag your wall for a while and then every month or so, come through and pressure wash it smooth and clean again. That way folks have a place to do their thing but you can wipe the slate clean when it rains or every month or something. It allows the art to be temporary which somehow makes it more special because you have to see it before it's gone.

  • Is there more "polar" liquid than water? I found various metrics for polarity (it cannot be expressed as a single number - that is only approximation because iduction, resonance, dipole moments etc. etc.) but typically alkanes are least polar (nonpolar) then the table goes through organics, alcohols and finally water. Is it possible to go further? Maybe liquid hydrogen fluoride? Supercritical carbon dioxide?

    • @@agnelomascarenhas8990Thanks, this is the magic word. By this measure, e.g. sulfuric acid (ε = 100) and formamide (ε = 111) are even more polar than water (ε = 80.1).

  • Missed opportunity when you wet the ferrofluid I was hoping you would try applying a magnet from below.

  • This reminds me of junior high when people would write on desks with permanent marker as a joke and then they take it off afterwords by writing over it with a dry erase marker and then removing that, then it lifts both off.
