Test tubes for new flavors

[Ms. Trixy]

I just saw these on Amazon and had to share. This would be perfect for a test of a new flavor. Small, slim, easy to shake and has a lid. $16.75 for 25. I'm going to get some. No waste!

I considered getting test tubes when first shopping for mixing supplies. I still might! I had the same thought as you, that they'd be easy for mixing. Problem was you need a rack as well, so I didn't bother when first starting out. Also likely need to move any batches you wanna test after steeping to a bottle.
So, possibly a measure of convenience, for a little hassle.
