how does a car hang upside down, let go, and still land on its wheels? watch Tesla’s Roadster on the curved ramp underneath, fans pull air out of the gap between the car and the surface. seals help keep that air from rushing straight back in the result works like a suction cup: the air outside presses the car against the ramp. Tesla says the grip is strong enough to hold it upside down even while standing still once it leaves the ramp, a different system takes over the car carries compressed gas and releases it through small nozzles. think of letting go of an inflated balloon: air shoots one way, the balloon goes the other with nozzles around the car, those pushes can also turn it. push one way to start rotating, then counter that turn to bring the wheels back underneath before landing, downward jets push upward on the car to slow its fall. Tesla says the system makes tiny, rapid adjustments to keep it stable there’s a catch: every burst uses up some of the stored gas. how long it can stay airborne depends on how much it carries and how quickly it spends it
