"Disgusting science (Pt 1)

We gave London an awesome "Disgusting Science" experiment kit, which my dad found online.

Yesterday, we made gelatin and prepared petri dishes to grow molds and bacteria. We also enacted peristalsis...the muscle contractions that carry food through the digestive track. In a nutshell, we put food in the balloon. It went down the "esophogus" and into the "stomach". We added "acid" to the "stomach" and kneaded to assist digestion just as muscles do. Turn it over and the balloon neck becomes "intestines"... In this shot, Tom and London continue peristalsis and the food becomes....homemade poo!!! Way gross ! Way FUN !!!
