Sam is learning all about the human body. And while I completely marvel at the miracle of a cell and it's 250 proteins and cell division and how our body makes over a billion new cells a minute, the experiments are downright messy. Here Sam is demonstrating cell division with jell-o and bananas. Jello cells are slippery suckers. And the scary part? In a day we're supposed to make Donna Digestion and some of the materials required scare me - over 4 pairs of pantyhose... what are we going to be pushing through our homemade intestines? I'm already grossed out.
