Toilet-Paper Air Stream

A long streamer shoots across the room. Ask students to predict what will happen. Direct air over the roll so the paper unspools dramatically. Key idea: Moving air transfers force to the lightweight paper. Ask: Can moving air pull out an entire roll? Safety and cleanup: Use cool/low setting; aim away from students. https://www.google.com/search?q=%22Toilet-Paper%20Air%20Stream%22%20science%20demonstration%20experiment
