We wanted to do a little experiment to see what household item would make the best vibration speaker. We tested an orange, a small cardboard box, a canvas sneaker, a metal flask, a glass jar (with black eyed peas), a mouse, a foam block, a plastic cup and a large cardboard box. Which item do you think will be the best?
