Time Capsule
A demolition crew recently uncovered blackboards in an Oklahoma high school dating to 1917. Apparently the workers just installed the new blackboards right over the old ones immediately after Thanksgiving. The writing and images on the boards were perfectly preserved and provide an interesting glimpse into our past, when this country was run by sane people. Piclick for more.

Looked at the multiplication wheel, still working on the mechanics of it.
