You won’t be surprised to find they roll at the same rate. Now shake one of them so bubbles form inside, then repeat the experiment. You’ll be delighted to observe that1. the shaken can wins the race.2. the shaken can loses the race.3. both cans still roll together.Roll a pair of identical cans of carbonated beverage down an incline.

In each hole bend the nail sideways and dent the holes so that when water is put in the can it will spurt out with a tangential component. Suspend the can with strings and watch it rotate as water spurts from it—noting its direction of rotation. Now empty the can; weigh it down at its bottom so that when you suspend it in water it remains upright as water flows into the holes.Question: What's the direction of rotation? 1. Same as before.2.
