how to split a pill

I saw a video of how to split a pill (tablet form). Place the pill on a hard, flat surface. Then place an index finger of each hand on either side of the score and press down. The pill snaps cleanly at the score. Just that simple. No tools required. I discovered that it works with certain pills even when the pill is not scored (like doggie's pain pills). I wish I can find the video again, but I haven't been succesful. If you find the video, please drop me the link. Thanks in advance.
