Why does a can of cranberry sauce roll so far?
Sounds like an experiment is in order --
Try rolling cans of various materials and see if you can identify the
similarity between the things that roll the greatest distance. What
about those that roll the least distance?
Hint: Try rolling a can of chicken noodle soup, then eat the soup, put
enough water in the can to nearly fill it. Freeze the can of water
(without covering it) and, once frozen, try rolling it again. Does it
roll a greater or lesser distance?
