The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid. A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object.
Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.
Hop up and down on the back wheel. Johnathan Ball [4] Pole Dance Doing a wheelie, take a hand off to grab an obstacle to go in a circle around. Johnathan Ball [4] Keo Spin From rolling backward, taking off one arm to get momentum into a back wheel spin. Named after Keo Curry. Johnathan Ball [4] Fish and Chips aka Fishy Whip.
Wheels can also lose traction when surface conditions reduce available traction such as on snow and ice. As an open differential delivers only enough torque to cause the "weakest" wheel to spin, if one drive wheel is stationary on a low traction surface (mud, ice, etc.), the deliverable torque is limited to the traction available on it.
A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.

Meteorologist Alex Wilson explains how a guy decided to slide down it backwards with a GoPro strapped to his chest. It's hair- raising enough to go down this waterslide the right way. Look what ...
