We are in the midst of our unit on SOUND!!! Take a look at us here, as our lovely singing voices cause salt to bounce on the lid of this Pringles can. Why is this happening? Does the pitch or loudness of our voice change the way the salt reacts? This is an awesome experiment to try again at home! Little brothers and sisters are sure to enjoy!
