SSI Shredding Demonstrations

I'm sure you've seen shredders that chop up documents. Once in a while, you may have run across one that minces credit cards as well. At this gallery, however, you can see clips of real shredders doing some real work. By that I mean splintering railroad ties, demolishing a steel drum full of concrete, and even turning an entire BMW into fist-sized pieces. Now that's some freakin' shredding!
