I think I want to begin freezing yeast that I have washed. I read where a good vessel is 1.5 ml test tubes with screw on caps. Where can I get these on the cheap? (I found one place online where I could get 40 of them for 13 bucks but then when I added the shipping it nearly doubled)
Also- I read I can get glycerin at any drug store, but hell, I don't even know what it is besides a Bush song from the 90's. What is it and what does it look like in the store? Is it on the shelf like a bottle of aspirin would be, or do I need to worry about the Meth cops putting me on a list?
