A BB is a little metal pellet about the size of a ball bearing. BBs are
made for shooting from air guns known as BB guns. Daisy is one of the
prime manufacturers of BB guns and BBs and on their web site
http://www.daisy.com/index.html they have a page of links to suppliers
http://www.daisy.com/wheretobuy.html
If you can't get BBs, probably any small round piece of metal would work
in the experiment.
