Great for demonstrating difficult-to-explain resonant waves such as propagation, reflection, and interference. Two cast metal supports, 15.25” tall x 9.5” depth, are extended by connector rods making a frame. A white cotton cloth backing is stretched between the frames to help make the demonstration...
A miniature model of the human skeleton, 16-1/2” (42 cm) tall. Constructed of durable PVC plastic, it features a spring-mounted jaw and removable arms and legs. The skeleton includes a rod mount and black plastic base. Overall height when on the stand is 18.9” (48 cm) tall. Articulated...
A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction...
