I'm not sure about 2012, but the 2015 igNobel Prizes carried a cash award of a trillion dollars (in Zimbabwe currency).

It has to do with your regular walking gait. It sets up a rhythm in the liquid that only builds on itself.
Apparently you can stop it happening by making sure your walking is not rhythmic.
Doing that would also avoid attracting the "Sand Worms of Dune". Always a good thing.

Hope that helps..
