From the author: “In this video I put a drone in a vacuum to see if it can still fly. I talk about how drones need air to fly unlike rockets. Then I put the drone in the vacuum and as I’m sucking out the air I try to fly the drone.
As the air is removed the drone cannot create lift and it is grounded. Then as I let the air back in the drone lifts off. Then I show how a rocket (my balloon) can still fly in a vacuum.”
