Ping-Pong Ball in Air Stream

The ball floats and follows the tilted air stream. Ask students to predict what will happen. Point dryer upward and place ball in the stream; tilt slightly. Key idea: Fast moving air and surrounding pressure keep the ball centered. Ask: Why doesn't the ball blow away? Safety and cleanup: Cool setting only; secure hair. https://youngscientistlab.com/science-starters/science-at-home/bernoulli-balance/
