Cheerios: Here comes the science
Ever wonder why your Cheerios clump together in the bowl of milk? Dominic Vella has your answer.
Basically, it sounds like what happens on a waterbed. (Get your mind out of the gutter.) When you put one Cheerio in the milk, it creates a dent in the surface. When you put another Cheerio in, it creates its own dent, and when they get close enough, they fall into each other. Just like when you and your sweetie get too close and roll together on the waterbed.
