This video is used by docents at CMA to show how glass can change from solid to fluid and back again. The artists at Jason Antol Studios in Columbus, Ohio, graciously performed the demonstrations on camera. The 10-second on-screen countdowns allow visitors a chance to answer each question. As used in the exhibition Chihuly Illuminated, the video is silent. Here it's presented with background music. Chihuly Illuminated is on view at CMA through July 4, 2010
