were formed by blowing air into honey sandwiched between two
transparent acrylic plates.
It was a little tough to take photos while blowing.
Air was pushed into silicone oil using a syringe in these experiments.
The experiments were carried out with Ms. Ikeno, Ms. Inoue, and Ms. Funakoshi during the open days at the department of physics of Nara Women's univ, Nara, Japan, 2007.
In the right hand video, there were small bumps in a square lattice on the surface of the bottom acrylic plate.

starch was dried naturally for a week.
The left photo was taken with transmitted light from a fluorescent tube, and the right photo, with natural light.
The size of this acrylic container was 30 x 30 cm and tilted slightly.
The thickness of the starch layer increased from about 1mm to 6 mm in the container (from right to left).
