We were so busy Friday with our dry ice experiments that we didn't get to make our Halloween Screamers. We read "The Magic School Bus and the Haunted Sound Museum" and learned that sound is made by vibrations. We put a hex nut in the balloons and blew them up. We made an eerie noise by swirling the balloons to spin the hex nuts inside. It was cool to compare the different sounds made by different size nuts.
