Explore flour and compare its characteristics to common examples of solids and liquids, in this video produced by WGBH. Observe the properties of flour, a wooden spoon, nuts, water, and oil. Flour can be poured and take the shape of its container, like a liquid, but it also can be picked up and held, like a solid. Collections of pieces, such as the particles of a powder, may have properties that the individual pieces do not have.
