Let’s Get STEAM-y: A Petri Dish Poll


So, I have this nifty set of petri dishes to play with…ten of them! Ten lovely, unused, just-waiting-to-harbor-something-icky petri dishes. Can you imagine the fun??? 🙂

Well, you’ll get to participate in the fun (woot!) because I’m going to let you pick which yucky (or not so yucky?) surfaces get swabbed and cultured! Do you want to see what sort of gross grows from the bottom of my purse? A toilet seat? ( I hope that one would be disappointing since I clean those suckers every day.) 😉 What about a refrigerator shelf or a piece of raw chicken? A dog paw? A dog mouth?

Just let me know your suggestions in the comments! I’ll leave comments open for a week and take the ten most popular suggestions. (If there are fewer than ten, I’ll just get creative.) 😉



What about you? Have you grown anything nifty in a petri dish lately? Or, perhaps, in your refrigerator or teenager’s room? 😉

Interested in growing your very own icky stuff from your very own home? You can snag this awesome set of petri dishes and swabs from Amazon (where I’m totally an affiliate) for just under $16.00.

    Your mouth and the dogs mouth. 🙂

      Yessssssssss! (I can totally see myself brushing my teeth for like an hour before swabbing.) 😉
