Why does my cereal get soggy?

Students encounter liquids everyday, but a lot of times it seems that the liquid just disappears: milk absorbs into cereal, and water from a bath absorbs into a towel. Where does the liquid go? We tested some materials that have the ability to absorb liquids by trapping it inside of pores or small holes. We also observed that not all materials are able to absorb the same amount of liquid. Different materials have different saturation points. For example, a mop can soak up a big spill, but your favorite cereal gets soggy really fast. Today, kids created a tool with absorbent materials to soak up those liquids. At home, ask your kid what else they can absorb with their new absorption tool!
