Many Gel s and Colloids are thixotropic materials, exhibiting a stable form at rest but becoming fluid when agitated. Some Clay s are also thixotropic, with their behavior of great importance to Structural Engineering in Earthquake zones. Clayey ground can practically Liquefy under the shaking of a tremor, greatly increasing the effect on buildings. Ketchup is frequently thixotropic. Many clutch-type Automatic Transmissions use fluids with thixotropic properties to engage the different clutch plates inside the transmission housing at specific pressures which then changes the gearset. Fluids which exhibit the opposite property, in which shaking for a time causes solidification, are called Rheopectic and are much less common. Etymology: Greek ''thixis'', touch (from ''thinganein'', to touch) + ''-tropy'', ''-tropous'', from Greek ''-tropos'', of turning, from ''tropos'', changeable, from ''trepein'', to turn.
