I have on my high heel shoes as I am crushing up a few boexes to put in the trash. As i step on each box I say things like," you want me to crush you under my foot like this box," or" want me to crush you under my foot?" Over and over I my heel into the boxes to get them to crumble and come apart right under my foot. I get each box very flat before I move to the next box. Each box is a different size, you will have to find the box that best fits what I will be crushing on you.
