Slinky Waves Two Ways

The slinky carries transverse and longitudinal waves. Ask students to predict what will happen. Show side-to-side and push-pull pulses. Key idea: Waves transfer energy while the material mostly oscillates in place. Ask: Does the slinky itself travel down the room? Safety and cleanup: Two-person teacher/assistant demo or low table. https://www.google.com/search?q=%22Slinky%20Waves%20Two%20Ways%22%20science%20demonstration%20experiment
