I promised you pulley pictures. Here they are. This is a double-pulley built by a group of sixth graders. It is being used to lift a plastic cup full of pennies. Future science teachers, it might be a good idea to start hoarding pennies now; they are sooo useful. Film canisters, plastic egg cartons, and POM juice bottles are also worth saving. Posted by Hello
