When I was a young lad, doing science experiments in the basement of a friend's house, we used to get all our supplies at Fisher Scientific.

You can find them on the web at www.fishersci.com.

They should have what you're looking for.

Good luck.

Hello vgeorge,

Please see https://www.sciencebuddies.org/science- ... =29&t=8496 for a discussion of another experimenter's encounter with the same problem, an optional source, and how he solved it.

Good luck, WW
