Anatomy of the foot. The foot is one of the most complex parts of the body. It is made up of 26 bones connected by many joints, muscles, tendons, and ligaments. The foot is susceptible to many stresses. Foot problems can cause pain, inflammation, or injury. These problems can result in limited movement and mobility.
Bricks and tiles. Bricks and tiles are made from clay minerals. When wet, the clay can be shaped, and then fired to make floor, wall, and roof tiles, as well as house bricks. Think about the properties of clay: Easy to shape when wet. Strong and rigid when fired. Impermeable when fired. A thermal insulator.
Plaster Walls. Once upon a time, in a land very far away, homes' interiors were framed by walls made of solid plaster, that heavy-as-lead (and about as much fun to handle) goop you slathered onto a lath with a trowel and manipulated with a float until you had a smooth finish.
