Paper Ball Stays in a Funnel

The ball can stay in the funnel instead of blowing away. Ask students to predict what will happen. Place ball in funnel and blow through the narrow end while tilting. Key idea: Fast-moving air lowers pressure and surrounding air helps hold the ball in place. Ask: Why doesn't your breath push the ball out? Safety and cleanup: Individual clean funnel or teacher demo. https://www.google.com/search?q=%22Paper%20Ball%20Stays%20in%20a%20Funnel%22%20science%20demonstration%20experiment
