We discuss some of the properties of air; it is all around us; we can feel the wind; see its effects on trees etc. We use a pair of connected syringes to show that air can be squashed and that they can be used to transfer a force from one place to another. We explain the use of pneumatics in automatic doors. Real tipper trucks use a liquid instead of air, but we shall use air to make a tipping mechanism. The children build a model tipper truck and are then invited to design a cab to protect the driver The children can design and make their own special bodywork, limited only by their imagination.
