First, Peter had to draw a target on a big piece of paper. He was so funny about getting it just right.
Thankfully, the new expanded patio in the backyard was the perfect setup. This experiment was representing the way a sneeze can project germs super far. Before we popped the balloon Peter thought that it would probably go 35 inches.
We then popped the balloon and discovered that germs can fly a whole lot farther then we both thought. They traveled an astounding 85 inches. Now, I cringe whenever someone around me sneezes.
Another part of this requirement was aimed at teaching you how quickly germs can spread on your hands. Technically, you are suppose to use glitter when you are shaking hands (see video), but since we have a strict no glitter policy at our house we used black craft paint instead. It did a great job and I think the boys now understanding of how germs spread. I just have to remind them about the "black paint" and they go running for the soap/water in the bathroom.
Another fun part in this section of the cub scout manual was the project of growing mold. We tried two other attempts before this one, and I so thankful this one finally worked. I had my doubts, particularly around Day 4 when I didn't see anything, but by Day 7 it was looking really gross.
It was interesting to see the different spots where it grew first. The banana went first, then the cheese, and last the bread. I have a feeling we'll be doing this experiment again when we are ready to pull out the microscope and look at rapid mold growth. Now, that will be cool.
