The French philosopher Voltaire tried to weigh the air. To do this, he inflated a bull bubble with air, weighed it, then released the air from the bubble and weighed it again. The bubble, empty and filled with air, weighed the same, from which Voltaire concluded that air was weightless. What is his mistake?
The weight of the bubble with air increases by as much as the buoyancy force acting on the inflated bubble increases.
