You may all think this is crzy, but I've always been amazed by cereal. First, there are so many ways that simple grains can be manipulated, and then, there are things like rice krispies, which are completely different from puffed rice, and I have no clue what the difference is. Then, you have shredded wheat. How the heck to they get wheat into that shape??? I could go on and on... What about Krispix, which is one color on one side, and darker on the other--each side a convex grid. I've always wated to take a tour of a cereal factory. Has anyone done this?
