Bacteria Growth Science Kit

Did you know that the keyboard you use every day is probably harboring more bacteria than a dog’s butt? Don’t believe it? You can see for yourself with the Bacteria Growth Science Kit ($25), and a little patience. This kit includes everything you need to culture up to 20 samples from any germy surface you’re curious about, plus instructions for experiments to see how growth is affected by various factors. If this doesn’t convince the kids to wash their hands, nothing will.
