Ok, I'm gonna go insane. Does ANYONE know where I can get a large quantity of plastic test tubes approxamately 25mm (1 inch) in diameter?? I've done internet searches, checked all kinds of plastics suppliers, science lab suppliers, even cookware suppliers (don't they use test tube-looking things for spice racks?). They need to be as close to 25mm as possible, and need to be plastic. Doesn't matter how long they are. Can anyone PLEASE HELP MEEEEEEE???
