Hi All. We are working on an exhibit showing how soap films form minimal surfaces and in general would like to illustrate math concepts using soap bubbles. Will you help us by telling us what exhibits exist at other museums, especially having mathematics connections? We would like to contact those places for advice on devices for making particular bubble "assemblies", controlling evaporation, handling the mess if visitors handle bubbles, how to form difficult surfaces such as Costas-Hoffman minimal surface. Thanks for your help. Joel Clark Science Center of Connecticut [log in to unmask]
