Readily available low-cost wireless microcolor cam systems are now small enough to mount in or on small toys and they are durable enough to withstand typical radio-controlled airplane crashes. These cams are an invaluable tool for the physics classroom in that they allow students to visually place themselves in the “shoes” of the bodies physics teachers describe and use everyday in the physics classroom.
