Explain this same concept, but so that a 3rd grader could understand it.

Right, in the simplest terms, porpoising is an aerodynamic phenomenon that F1 cars began to suffer from after the adoption of the so-called ‘ground effect’ philosophy, where air is sucked underneath a car to pull it down onto the track at high speed, rather than over the top of the car to push it down. With us so far?

The trouble is, the faster you go, the further a car wants to be sucked to the floor. And if it gets too close it can cause the airflow to stop - or ‘stall’ - meaning the downforce created suddenly drops off a cliff. At that point, the cars spring upwards.

Once the car’s floor is clear of the ground however, the flow of air kicks in again and the car is sucked downwards once more. This aggressive bouncing is porpoising.

F1 cars have a trick to go fast, instead of air going over a car, it goes underneath the car like a tunnel. This helps the car stick to the ground for better grip. When cars go fast, something strange happens, the cars get too close to the ground and the air doesn't flow properly anymore. The air stops flowing and the car no longer is being pushed down and instead springs up. Once the car springs up the airflow starts working again and pulls the car back down but then the cycle repeats. This effect is called porpoising.
