I recently made DIY kitchen wipes, which are meh, mostly because I don't like the way they smell. These baby wipes actually sound a little more intriguing.
Posting to add that I thought it was wasteful to leave the core in, because it absorbs too much, as the video clearly shows. I removed it before adding the liquid. It worked just fine. Stick your fingers down into the core, fold/smush it in half or more and it will slip out easily, so no "secret sauce" is lost.
