The 7' rule is simply a blown up version of a 12" rule. Everything 7 times
bigger. Sure, you can estimate a bit better, but you wouldn't really want
to try to calculate with this thing. Its massive!!
One of my science teachers had one of those. I'm convinced that's
about the best way to teach basic slipsticking.
