Stop Motion Animation of Falling

I wanted to use an object that could squish, so I decided to use a beanbag. I initially tried to shoot the sequence from directly above. Unfortunately, the beanbag wouldn't stay in the shape I wanted. Also, the shadows were kind of strange. So I shot the sequence again. When I shot it again, I used duct tape to tape it to the wall. Then, I slowly moved the beanbag down the wall with the tape until I reached the box at the bottom. I then squished parts of it and slowly flattened it.
