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.
Vacuum is space void of matter. The word stems from the Latin adjective vacuus for “vacant” or “void”. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure.
