Zusammenfassung:	Three-dimensional foams were produced by mixing air and water+Extran solutions in a shaker. Long-time observations revealed that bubble radius distributions become stationary. Differently from the maximum-entropy coarsened distributions for 2D foams, we found radius distributions to be Gaussian. The stationary distributions are found above a threshold shaking energy. Foams created at the threshold store finite energy which increases roughly linearly with applied energy.
