Explosion of a Balloon Filled with Hydrogen Gas
March Meeting 2010
Six frames from a high-speed video movie of the explosion of a balloon filled with hydrogen gas

The images show the explosion of a balloon filled with hydrogen. High-speed videography at a few thousand frames per second makes it possible to observe in detail the sequence of events after the balloon has been lit with a match. Note in particular that the balloon has popped and disappeared before the actual explosion unfolds.
At the University of Chicago we have developed an annual event entitled "Physics with a Bang!" aimed at the general public. This event includes lecture demonstrations (some loud, some amazing and some simply beautiful) and uses high-speed video to show details too fast to see with the naked eye. Also part of this is an open house with tours of our research institute's labs and hands-on demos for kids. In this evening's talk I will introduce you to some of the highlights and try to stimulate your own interest to develop unique outreach material to engage students and the public in the wonders of physics and how it relates to their everyday lives."
