ELI5:The Cheerios Effect

As I poured my morning box of honey nut Cheerios, I read the back of the box. It explains, that if you put two honey nut Cheerios in a bowl of milk, they will eventually gravitate towards each other and stay together. I tested this out and it works! Why do my honey nut Cheerios gravitate towards each other and then stay together?

It's because they're both held up by surface tension, which pushes the milk down ever so slightly. Think of a flat piece of plastic with water droplets on it. Wherever you push down, the water droplets will converge there. Both cheerios are pushing, so each will be drawn to the other. Once connected, they have made themselves an even bigger bowl and will stay together in there until you eat them.
