In this book in the Kids Can Do It series, kids can learn how to turn a pair of old sunglasses into wacky windshield-wiper glasses and an ordinary box into a "gift" box that rumbles. Kids begin by learning about the parts of a basic circuit and go on to build switches and battery packs. Projects are made from recycled household materials -- such as cardboard tubes, clothespins and empty shampoo bottles -- and powered by batteries. Helpful hints and troubleshooting tips ensure success with every gadget
