Atlanta Test Tube

Still looking for a local source for a test tube. Would also be nice to find a local source for petri dishes.

What size do I need? Enough to have room for 5 mls of peroxide and a piece of mushroom of banana. I would think that 10 mls would work.

I wonder if I might have an old test tube around somewhere in the garage?
