This is a video of a glob of non-Newtonian fluid dancing on a speaker in super slow motion (previously: this one not in slow-motion but with an explanation of what a non-Newtonian fluid is). At one point I'm pretty sure I saw the devil's face appear. Of course that might have just been my imagination. Although I swear I heard it say, "GW, this is the devil speaking." Again, probably just my imagination. Then I felt a piercing pain behind my eyes and my head burst into flames. Now I'm starting to wonder (plus laying in the bathtub waving a Bible and crucifix).
Keep going for the video, but skip to 1:40 unless you're into jibber-jabber.
Thanks to mac, who's favorite non-non-Newtonian fluid is Capri Sun. Mmmmm, mine's Hawaiian Punch. Jk jk, beer.
