Running on water: On the earth and on the moon
It would be even better on the moon. Yes, here on earth you can run atop a pool of water-mixed-with-cornstarch, as people are doing in this video: But you could also run atop a pool of pure water—if you and that water were somewhere that has weaker gravity. The moon is one such place. An […]
Jogging on / kitchen-sinking into muck
In this video for New Scientist, Chris Chiswell jogs on the non-Newtonian fluid known as cornstarch-mixed-with-water, until he stops jogging and sinks into it, demonstrating the non-Newtonianness of the muck. The ingredients of the goo—cornstarch and water—are commonly found in kitchens, thus this demonstration shows an example of kitchen sinking. (Thanks to investigator Alicia Weston […]
