Photos from Mayfest 2007, Corn Starch Demo
in the Quad
This demo shows how some fluids can behave either
as a liquid or a solid. When the cornstarch mixture (2 lbs cornstarch to 1 litre
of water) is put under a blunt force, it behaves as a solid. When not stressed,
it behaves as a liquid. Thus, one can walk on this fluid without sinking,
amazing!
See a video clip from you-tube here!

SPS Prez, Jess McIver servin' up some corn-starch to a
couple of future physicists! |

SPS member Andrew Powers explaining the physics of this
non-Newtonian fluid. SPS member Tom Glodstein just behin Andrew. |

SPS member Tom Goldstein, caught doing one of his classic
areal moves of the day. SPS-er Andrew Powers on deck! |
