Bernoulli Ping Pong Ball in a Funnel

When you blow through the narrow end of a funnel with a ping-pong ball inside, the ball stays suspended in the funnel rather than flying out. This happens because fast-moving air has lower pressure than slow-moving air (Bernoulli’s Principle). The rapid airflow creates a low-pressure pocket around the ball, and the higher atmospheric pressure underneath pushes it firmly into the funnel.

• Velocity Difference: As you blow air into the narrow end, the air speeds up as it passes the ball
• Pressure Drop: According to Daniel Bernoulli's 1738 principle, this high-velocity air results in lower air pressure above and beside the ball
• The Pushing Force: The still air beneath or surrounding the ball has higher pressure. This higher pressure pushes the ball upwards or forces it deeper into the funnel, completely defying gravity
• The "Inverted" Challenge: If you hold the funnel upside down and blow through it, the ball still will not fall. The pressure difference pins the ball against the sloped sides of the funnel
