Awesome Experiments in Light & Sound
These totally awesome, kid-friendly experiments teach the scientific basics of light and sound. And they're easy to carry out, using the most ordinary materials found around the house. Just grab a boom box, toilet paper tube, rubber band, or drinking straw to create a little smart magic. And it's fun to make cereal dance to the music and watch light bounce off a mirror and hit a bull's-eye. Hear your heart pumping through a funnel and tubing. Build a "ray maker" to display the visible spectrum of light in a glorious rainbow tray. These experiments will change the way you look and listen to the world around you!
