Does Bernoullis principle work?
When I’m not flying airplanes, riding my bike or helping to raise my grandson, I am teaching math, art and a little science to school aged children. Once in a while we get caught up in a flight theme where we talk about airplanes, birds, aeronautical terms and experiments. One of my favorites has always been folding and stapling a sheet of paper into an airfoil and then talking about how wings fly using Bernoulli’s Law. We blow on the leading edge of the paper airfoil and I explain how the air on top has to move faster than the air on the bottom so that both halves will meet at the end of the airfoil at the same time. This provides the wing with “lift.” After that explanation I always feel warm and fuzzy thinking I had passed on the important information all young people should know as they enter the adult world. I believe aeronautics should be part of one’s upbringing as is math, reading, writing, music and art.” I felt happy that I had done my part by bringing my students state-of-th
