Subject: pinhole looking for magnetic squish balls--I know I saw them in
a catalog!
There's a great activity that Paul showed one summer.
You put a magnet inside an earth squish-ball and then
sprinkle staples over it. The staples line up with
the magnetic field. Recently, I saw a science catalog
that's selling these so you don't have to cut open a
squish ball. However, my department didn't keep the
catalog and now I can't find them anywhere. Does
anyone know which company was selling them? Thank
you!!
