Round wooden panel used to support the Foucuault pendulum suspended from the inner dome of the Kansas State Capitol. The Foucault pendulum was installed at the Capitol on November 15, 1945 by Dr. George W. Davis of Ottowa. The orginal pendulum weighed 105 pounds, although its weight was eventually increased to 205 pounds. It was suspended by a 163 foot long piece of number 14 wire. The pendulum's motion was started each morning by custodian L.D. Robinson, and it swung in a 14 foot arc.
