ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
In an attempt to show that sound vibrations can move objects, I put a bit of
salt and pepper on a piece of plastic wrap which was stretched tight over
the top of an aluminum can. I then held a metal cookie sheet a few inches
above the wrap, and whacked it with a metal spoon. Indeed, the salt and pepper
jumped!
I then continued to whack the cookie sheet ten more times, and the salt and
pepper started to line up in rows! When I was done, I had three or four neat
lines of salt and pepper on my plastic wrap.
Were the salt and pepper bits lining up based on the frequency of the
vibrations I was creating? Or was something else going on?
Thanks so very much!
