| Wed April 2nd 2014 16:00 ZH286 | Seminar | Giant soap bubbles Jacco Snoeijer |
Details:A small drop on a substrate takes the shape of a spherical cap. A large sessile drop becomes a puddle, flattened by gravity, with a height that does not exceed the capillary length. In this talk we consider the equivalent problem for "sessile soap bubbles", floating a bath of soapy water. Due to the limited weight of the bubble, gravitational effects are observed only for giant soap bubbles, with radius of about a meter. We present experimental and theoretical results for the bubble shape, and point out the relation to the catenary problem and giant inflatable domes. | ||
