 ==== `gtGenericFaller` ====
-TODO. The purpose of this gear is not clear yet.
+This gear behaves like a virtual ball. It collides with its surroundings and bounces around but doesn't affect the environment or other gears in any way. It appears as a red circle, unless it is made invisible by setting the gear state. It also supports the gear state `gstNoGravity`. It gets automatically destroyed when its `Timer` is up.
+
+The density, elasticity, friction and radius can be changed.
+
+ * `Radius`: Radiuis of the “ball”
+ * `Timer`: Lifetimer. Needs to be set explicitly to a positive value, otherwise the gear just dies instantly
+
+This gear could be useful for some testing or as a dummy.
 
 ==== `gtWaterUp` ====
 Causes the water to rise.
