New Soap Films
Dip one of the frames in a pail with soap water. Carefully pull it out and observe the fantastic structure that has been created.
These racks were contributed of Professor U Brehm (TU Dresden). One supplies a marvelously round soap skin despite its approximately angular form. With the second a Moebius Strip develops (you may have to puncture the soap skin in the center). The third rack is an open wire and nevertheless forms a closed soap skin.
