Blows and maintains
PRESENTATION: A lightweight ball can float in airflow due to the fact that a flow with speed has lower pressure. The ball remains in equilibrium, compensating its weight with the force exerted onto it by the greater atmospheric pressure surrounding it. A flow like this can be created using a hairdryer, an air pump, an air tube, etc.
