No Halloween at Northwestern is complete without Eberhard Zwergel. For more than a decade, the Chemistry Department’s senior lecturer and demonstrator has dazzled audiences with his annual Halloween-themed science show.

Backed by student dance troupes, a segment of the marching band, a few cheerleaders and a three-piece rock band, Zwergel and his team of undergraduate volunteers demonstrate the hotter side of chemistry with a lineup of demonstrations that usually end in an explosion of fire, a deafening bang or some combination of the two.
