Cavendish Experiment. You're setting up 4 Cavendish experiments for a classroom, right? You may have to make your own balls. Lead is the easy to cast. Plaster of Paris half-shells, seamed along the equator will work fine. Use Niobium wire. Less creep. Don't neglect to put each in a grounded Faraday cage, and watch out for drafts. Good Luck.

Why? Are you going to check to make sure Galileo was right?
I guess you'd have to ask some kind of lead company.
