"You take an old hard cover book with the spine facing away from the camera. You put like 3 or 4 of candies (e.g., skittles, mentos, gum drops) in between the pages (just inside the book - at the edge so they can be seen being crushed) and stand on it ON TIPTOE WITH ALL YOUR WEIGHT ON ONE FOOT to get it as flat as possible. After you've flattened those candies, then you take 3 or 4 more, putting them in between different pages and do the same thing. You would repeat a bunch of times until you've flattened a bunch of candies as much as you can like that." (I used mentos and gummy bears!)
