Noisy String

Study the science of sound while making fun (and annoying) sounds.

Last time, I left you with a challenge. We put a little sand into a glass of water and stirred it. Instead of moving to the outside edge, as we might expect, the sand gathered in the center of the glass. I left you with the challenge of telling me why.

Congratulations! Several of you got the right answer, and several more got it at least partially right.

This is still my favorite way to demonstrate the science of inertia. The demonstration is dramatic enough to make people tense in anticipation, even if they understand the science and have seen it done a hundred times. The science is simple enough for young students to understand, and with practice, even a first grader can successfully perform the demonstration.
