How does the Cheerio effect work?
The Cheerios effect arises from the interaction of gravity and surface tension — the tendency of molecules on the surface of a liquid to stick together, forming a thin film across the surface. Small objects like Cheerios aren’t heavy enough to break the surface tension of milk, so they float.
Why do bubbles clump together?
This effect is due to the fact that molecules of the liquid are more strongly attracted to each other than they are to the air above the liquid. As such, non-wetting objects on the surface of the liquid will experience an upward force due to surface tension.
Why does cereal go to the edge of the bowl?
Cheerios near the edge of the bowl float upwards along the curve of the meniscus to look like they’re clinging the edge of the bowl. In both cases, the movements of the Cheerios are determined more by the geometry of the surface of the milk than by any attractive force acting between them.
Why do Cheerios cling together?
The Cheerios stick together as a way of reducing the surface energy that exists in the milk-cereal system. A single Cheerio floating in milk does three things; it deforms the surface of the liquid, it creates more surface and therefore it generates more surface energy.
Why do Cheerios shrink in milk?
In the case of your breakfast cereal, the Cheerios can be considered milk-philic because the O’s create a small depression in the milk’s surface, forcing them to fall in towards each other.
Does cereal float in milk?

Does cereal with water taste good?
“The taste of milk conflicts with the taste of the cereal, whereas water does not. While still getting the same texture, water does not ruin the taste of cereal.
Why do Cheerios float in milk?
Why do Cheerios have a hole?
If you’ve ever wondered how they get those tiny holes in the middle of every little Cheerio, you’re not alone. It’s actually a pretty simple process. Once the dough is mixed, it’s forced through a die cut that forms it into the iconic looking O.
Can you eat cereal at night?
Cereal might be something you’d be more likely to eat in the morning than before bed, but there’s nothing wrong with eating cereal at night, provided it fits in with your diet as a whole. The idea that it’s bad to eat carb-dense foods — like cereal — before bed is false.
What cereal can I eat without milk?
Dairy-Free Hot Cereal Oatmeal and other whole grains, such as brown rice, quinoa or millet, make a great-tasting hot breakfast even without milk. After cooking them with water, add the sweetener of your choice and garnish your bowl with add-ons like walnuts, toasted coconut flakes, raisins or fresh fruit.
