metal ball for next lab
** **
** **
I looked ahead to the next lab and noticed that the ball will need to be metal since we'll be using a magnet.
Either I never got a steel ball or I've misplaced it along the way, because I've been using glass marbles for all the recent ball-down-ramp labs. I can't seem to find a metal one in my kit anywhere.
I am hoping to do the lab over the weekend while traveling in PA, and I wondered if you had any advice as to where I might purchase a ball similar to what should be in my kit. Or, if you happen to have extras, if there is a way I might be able to pick one up tomorrow before I leave town for the weekend.
Thank you for any advice you can give me on this.

I've emailed you regarding this. Hopefully we'll be able to arrange for you to get the steel ball.
