Corn Starch Holes by Merkt, Deegan et. al. , kast55555,

from the description of this youtube entry:

I found this clip on the net some time ago and did a voice over to it...I also put Booker T. and the MG's as the soundtrack...

the video comes from the research here

F. Merkt, R.D. Deegan, D. Goldman, E. Rericha, and H.L. Swinney, �Persistent holes in a fluid�, Phys. Rev. Letters. 92 184501 (2004)

what is it? the fingers are self organizing structures feeding off of the vibrational energy supplied to the goop.
