When you look closely where the cereal meets the milk it curves up, the same thing happens at the edge of the bowl. This is called the Meniscus effect. It gives you a U shape from the Cheerio in the middle to the bowl edge. A buoyant object will always be pushed up the liquid to the highest point on a meniscus. That’s what makes them stick to the edge of the bowl. When you drop in a couple cheerios into the bowl they are pushed together to the highest point of the bowl. A single cheerio will be pushed to the edge. This is why your cereal bunches together. The cereal is lighter than the water so surface tension holds the cheerios on top of the water. The water molecules like to stick to each other so much, and become strong enough to hold up tiny things. This time I tried a couple thumbtacks and the same thing happens. But the difference is the water around each thumbtack is curved down, where the cheerio is curved up. So this time instead of moving up the water, they fall down the water. When I take off the plastic piece of the thumbtack and put it next to a regular thumbtack they are not pulled together, but repelled to each other. They push the other away.
