Kids use simple machines every day without realizing it. Teeth are wedges and so are knives, forks, and thumbtacks. A lot of toys and playground equipment such as slides, which are inclined planes, and seesaws, which are levers, are also simple machines. Two appealing kids and their comical cat introduce familiar simple machines and explain how they work.
