Water Rockets

Posted October 19, 2006

Yesterday, The Wife and I were running errands when we noticed a class of middle schoolers standing in a field near our house.  The teacher was fiddling with a 2-liter soda bottle equipped with fins: a class-built water rocket.  We watched as they filled it up, pumped it up, and with a cheer, launched it into the sky.  It was great -- an inexpensive, interactive, and exciting demonstration of physics at work.  Instead of falling asleep over a book, these kids were screaming about the joys of Newton's Third Law.

Now that's education.
