Petri Dish Soap

This week's clever maker-entrepreneur award goes to Etsy sellers Cleaner Science, who make and sell these awesome soaps that look like petri dishes full of growing germs. They're easy to make (I presume), inexpensive to buy, light enough to ship cheaply, and totally original. Home run! Bonus: some include glow-in-the-dark spots!
