Wonder Wednesday 143: From Sand to Sculpture
Concrete is a composite material (something made of 2 or more different materials with dissimilar properties) that cures and hardens to a solid over time. It is composed of aggregate (coarse to medium grained particulate material) and cement (which is a fluid binder that sets, hardens, and adheres other materials). In our case in this project, sand is our aggregate and water and cornstarch are our cement. | Wings, Worms and Wonder
