Fault Simulator, Each

Need a tactile way to feel the motion of transverse faults and earthquakes? Who could "fault" that? This unusal hands-on lab consists of two durable plastic plates with sliding tab connections and instructions. Show how two tectonic plates slide against each other, generating great frictions. Simulate the mechanism that causes an earthquake by pressing the plates together. At the first hint of lateral motion, the slide past one another rapidly.
