How can I reuse or recycle … old test tubes?
An email from Kathy:
OK this probably isn’t going to be a common thing people will need to recycle but I was cleaning out a cupboard at work and found some old glass test tubes. I have no idea where they came from but don’t want to throw them away if there is anything fun to do with them.
They’re not spotless so they must have been used at some time, no idea what for, some of the stain look almost waxy, but now most of them are just dusty.
I remember a few years ago, there was a trend for drinking shots out of test tubes but if you don’t know what’s been in them, you probably shouldn’t be using them as glasses for your next party… I’ve also seen them used for single stem vases – but I guess you’d need some sort of holder too.
Any better ideas?
