Sure, the Hexaflexagon is fascinating all by its lonesome, but does it have any practical uses? Vi Hart shows us how to us the the multiple surfaces provided by the folding, flipping mathematical marvel to form a make a delicious concoction of beans, cheese, and guacamole. It's brilliant, if a bit messy.
Last week, YouTube's resident mathematical mind-blower, Vi Hart, introduced many of us to the topological wonder that is the hexaflexagon. If you haven't seen it yet, get your life in order and go check it out. In fact, even if you have seen it, go ahead and watch it again. Then reconvene with us here for round two…
