I am an English teacher but like to talk science sometimes. Some years ago, I had an air-pump wine bottle opener that with a needle into the cork pumped air into the bottle and popped the cork out. I liked using it because it was innovative and very cool. Once, I used it on a triangular-shaped bottle of sangria from Spain and the bottle exploded, which in retrospect seemed logical, and I learned a lesson: "science is everywhere," my scientist colleague used to say. Recently, I got in a rather in-depth argument with one of my students. We both agreed that the non-circular bottle shape caused the problem, and would every time. I said the bottle exploded because the triangular shape caused there to be different pressure at different points on the bottle surface area. He said that pressure was distributed equally to all points by the liquid, but the bottle exploded because the glass at different points was weaker than at others. Who was right? Selden Edwards
