How does it work?

While in Idaho we had many adventures with Aimee and the kids and our first one was to the science center. The kids had sooo much fun exploring and learning new things. It is also a fun place for adults. I admit I got stuck trying to figure out how this one puzzle worked and it drove me nuts until I finally figured it out.
