*****

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!
