I have on new shoes and a whole bunch new cans all sizes. I am going to crush these cans one by one till they are flat as the ground. I place my foot over top the can and press down using all my might till I hear that can crumble and crack under my foot. I have a few big cans that I need to use both feet in order to get it as flat as I need it to be. I love the way the cans feel as they give way under my foot. I wonder how fast you would give way if you were caught under my foot.
