Trending · Flying Roadster Part 2: How can a car fly with just air?
Air pushed out one way pushes the car the other way (Newton's 3rd law); about 10 nozzles, nothing burns.
How can a car fly with just AIR? 💨🚗
1️⃣ PUSH AIR OUT: squeeze air into a tank, then let it rush out of a nozzle. The air goes one way — the car is pushed the other way.
2️⃣ NEWTON'S 3RD LAW: every push has an equal and opposite push back. Just like a balloon you let go! Nothing burns — it's "cold gas". SpaceX's Falcon 9 rockets steer with cold-gas thrusters too.
3️⃣ THE ROADSTER: Tesla says about 10 nozzles push 4–5 times harder than the tyres can grip.
Push air back, go forward!
