As seen on Discovery Channel's "Time Warp", National Geographic TV and on-stage by invitation (twice) at America's largest science and engineering festival in DC, Keith uses bubbles - large and small - to explain liquids, solids and gasses, geometry, tension, and pressure. Keith builds beautiful sculptural creations (massive and miniature) with enthusiasm, humor and style. One moment he will be encasing a dinosaur in a bubble and in the next moment he's encapsulating an audience volunteer. Don't miss this playhouse favorite.
