Stretch the Chain and See the Light

Stretch the Chain and See the Light

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb. When the chain is stretched, the light bulb glows brighter. The explanation lies in decreased electrical resistance due to better contact between the paper clips as the chain is stretched.
