Wanted to give a heads up that there is some messy male feet included, so feel free to ignore if that part doesn't interest you, but there is some messy female feet too, so that's why I posted it.
They seem to do a lot of performance art with cake, but this was an interesting one: cake hopscotch. Yes, they use cakes in place of the hopscotch squares. I'll admit that I'm amazed they don't wipe out.
As an aside, I've seen a different performance artist do a game of "Pie Twister", where they use whipped cream pies (different colors for the circles), and the women play a game of Twister.
