Bob David went and built himself a 5,000 volt can crusher just because he could. That's what I love about people: they do things for no reason. Also, some of them smell good. But don't let 'em catch you sniffing! If you care how Bob built the thing you can watch the first two minutes, but you look ADD-y, so skip to 2:15 for the action. Cool, huh? Now, let's snort some Adderall.
