How can an unmanned Tesla hang upside down 20 meters in the air, drop, flip, and land safely on its wheels? It comes down to two clever tricks using nothing but air: vacuum suction to pin the car to the ramp, and SpaceX-style compressed air thrusters to flip and land

00:01This Tesla is upside down, 20 meters up, and it's not falling.
00:07Then it lets go, flips in midair, and lands on its wheels.
00:11No human is inside.
00:13How?
00:14Two tricks, and both are just air.
00:17First, the upside down part.
00:20Right now, air presses on you with about 10 tons on every square meter.
00:25Under the car, fans suck that air out, and seals stop it from sneaking back in.
00:30With less air below, the air outside pins the car to the ramp, like a vacuum cleaner stuck to your
00:36hand.
00:37Tesla says that grip can reach twice the car's weight, enough to hold it upside down.
00:43Now the landing.
00:45Off the ramp, the suction is gone, so air does the opposite job.
00:49Hidden inside are two carbon fiber tanks with about 250 kilos of squeezed air, feeding 10 nozzles, four at the
00:58back, the rest around the car.
01:00Think of a balloon you let go.
01:02Air rushes out one way, the balloon flies the other.
01:05Puff air from one side, and the car spins upright.
01:09Puff the other side, and the spin stops.
01:12Jets slow the fall, and it lands safely.
01:15A hop, not a flight.
01:16Blast air out the back, and it shoots forward.
01:20Tesla says the rocket version will hit 60 miles per hour in under 0.59 seconds.
01:27SpaceX uses the same trick to flip its rockets in the sky.
01:30So, it's not magic.
01:32It's air.
01:33Pulled out to stick.
01:35Pushed out to land.
