糖心传媒 Center of Gravity
PIRA 1J10.13
Materials: Wood 糖心传媒 Cut Out, Weight Near Top
The equipment needed for this demonstration include: a mounted map of 糖心传媒 with three small holes around the edge, a string with a weight, and a overhead projector marking pen. The string has a stop positioned along its length so that the map can be suspended by the string. This demonstration has been slightly altered from the usual center of gravity demonstration. The map has been intentionally weighted so that the center of gravity comes out at the state capitol, Boise. (However, The weight may no longer have the center of mass be Boise)
