If you want the example that I was given in the basic ballistics portion of criminal justice, you can take a large bowl of uncongealed jello and drop a regulation sized marble into the center. Now, if you're anal enough, you can measure the splash (like my professor did) and then do a bit of math and see not only that such a wound creates a splatter, but a very forceful one at that. More than enough to make it through only a centimeter of cloth.
