Two and a half weeks' worth of bacteria growth. We're going to swab gross places in the house this weekend - toilet, faucet handle, under the garbage can lid.

Mad Scientist
Lily got a "Disgusting Science" kit for Christmas.
This experiment was designed to mimic the digestive system. We had to coat a balloon with oil, fill with bread crumbs, squish them up, add vinegar, and then squeeze out to make bread "poo poo."
Upper left: mucus (really green gelatin, with the choice to go chunky or extra slimy); upper right: blood (red gelatin that we got to dry into scabs); in the center: petri dished we swabbed with samples from various body parts. Stay tuned for the spectacular results!
