Over the years I’ve ended up with quite a few sample-size tubes of toothpaste. I dislike the strong, lingering flavors of most of these toothpastes, so I normally use Tom’s of Maine (or Trader Joe’s equivalent, but not Tom’s of Finland) plain mint toothpaste, so I had a bunch of tubes which were past expiration and needing to be thrown out. 23 tubes (and four small sample packs), in fact.
Before throwing them out I decided to squeeze them all into one bowl. Next I stirred it all together, found that a spoon will almost stand up in it, then put some on my toothbrush and brushed my teeth with it.
