I have to admit, I would probably freak out if I saw Petri Dish Soap in a shower. After I realized what it was, though, it would probably be fine.
Petri Dish Soap is made to look some famous bacterias, including Salmonella and Influenza. These soaps come in a variety of scents, meaning that you'll smell good all day in the lab. All of the soaps in the gallery plus many more are available by clicking on the links to your left. Science has never smelled so good.
