We are working on a series of exhibits funded by the National Science Foundation. They series of called "Mathmagical Toys" and each is intended to connect a toy with one or more mathematical ideas. We've engineered a soap bubble machine that makes a stream of 1' bubbles at about 2 second intervals. We are going to let them drop about 13 feet into a very large circular catch tray. Visitors can try to pop or deform the bubbles with two air vortex guns. We interpret the bubbles mainly as examples of minimal surfaces. We also mention interference effects and vortexes. This exhibit is the fourth in a series. Each exhibit unit has a subtitle and a title, with the title being either a toy or suggestive of a possible toy or suggestive of a place that kids associate with play. The subtitle echoes that and emphasizes the main math point. The subtitle is set: "Soap Bubble Geometry". The contenders for the main title are below. Please pick one and reply or e-mail me. We're in a rush, as ever, since the title we had chosen was booed down by an angry mob. Bubble Mania The Bubble Factory The Bubble Zone Bubble Party Bubble Invaders The Bubble-ator or Bubblator Bubble Blaster Bubblemaker or bub-bub-Bubblemaker Bubblemath The Mathtub
