Jr Engineering - Hot air balloons

Today at jr engineering, we learned about hot air balloons. We took a toaster and placed a cone out of cardboard on top to make a bag rise. It was really cool to watch it rise without a blower and just heat. The kids also made baskets and attached them to helium balloons and added paperclips as necessary to weight it. We also began construction of a 5 foot mylar balloon and although we didn't complete it yet, it should work well once we do.
