This was our first attempt. You can see parts of the carpet and the inside of the box, and it looks like the can drifted up a bit, but the real problem is that it's really blurry. We decided the slit was too wide and that was causing the camera to see different parts of the can as the slit passed by. It turns out there's something else funny here, but we couldn't tell because the image was so blurry.
