Experiment:

Question:

What does Mr. Santa observe, when he carefully touches the metal can with one finger?

A) Nothing happens.

B) The tinsel threads first wrap themselves around the wire, then they hang down relaxed.

C) The tinsel threads first wrap themselves around the wire, then they repel each other.

D) The tinsel threads first repel each other, then they hang down relaxed.

Advice of the day:

If you don't have tinsel, you can also cut thin plastic bags from the fruit department of a supermarket into thin strips. More tips: - Put another wooden block on top of the can (better contact to the wire) - use as large a PVC part as possible, a piece of drain pipe worked best with us. - The person who charges the PVC piece should wear shoes with rubber soles, take off shoes for touching (grounding).
