New fissures opened on Mount Kilauea in Hawaii earlier this month, resulting in some fountain-like eruptions of lava. This molten rock is a non-Newtonian fluid with shear-thinning and thixotropic properties. This is what allows the lava to flow long distances before it cools and solidifies. (via jpshoer)

If you enjoy FYFD, why not take a minute to recommend us in the Tumblr directory? Thanks!

While this video is not strictly about fluid dynamics, there are some pretty cool high-speed fluids moments in it. Watch the reaction of the gelatins as objects hit them and observe the deformation of the water balloons as they strike. (via JetForMe)

So the video about the ooblek was clearly filmed at CU Boulder. Do you go to school here?
Also, you should enable disqus comments or replies to your posts!
Nope! I have connections to three different universities (one of which has been featured here), but none of them is CU Boulder. I just found that video on YouTube.
In shear-thickening, non-Newtonian fluids, disturbances make the fluid more viscous (“thicker”, more resistant to motion). This is well-demonstrated by putting some on a speaker and turning it on! #
