Researchers at the Oak Ridge National Laboratory were experimenting with a new photon-based 3D-printing technique, and figured the best way to demonstrate their machine was to make the world’s smallest fidget spinner. Despite being just 1000 microns wide, as thin as a human hair strand, the crafting is so precise it actually does spin. Not that you can see it of course.
10. Licki brush
This product is basically a synthetic cat tongue for the perfectly normal human being that wants to brush their cat like their mother would. Just stick it in your mouth like a baby’s pacifier and use the extended “tongue” to simulate grooming your confused feline. All the love, none of the cat fur in your mouth. Win-win.
