Catenary on a Cold Steel Rod
Amanda Barnes
Water droplets hang from a cylinder, held by surface tension. The droplets, formed by gravity and surface tension, are almost catenary shapes, acting as lenses.

Dry ice placed underwater forms bubbles of CO2 filled with water fog. The bubbles are illuminated by a flash. The room lights made the red smear while the shutter was open.

Interstices

Oobleck

Pouring a cornstarch/water mixture shows "non-Newtonian" behavior, as the faster moving fluid is 'stiffer' than the slower, pooled mixture.

Worlds Colliding

Spin ... Color
Mu-Hong Lin
Colors caused by interference of light waves show thickness variations in a thin layer spin-coated onto a silicon wafer. The center of the spin is near the middle of the image.

Burbling

Dyed water, excited by a loudspeaker from below.

Oil Fingering
Erik Hansen, Phil Bollam, Justin Cohee, Barry Whittaker and Hsin-Jui Wu
Looking down on a thin layer of oil sandwiched between sheets of plastic. Air was pulled into oil as the top sheet of plastic was lifted. The interface between air and oil is seen.

Solid in Gas in Liquid
Matthew Blessinger, Dung Dinh Luu, Kevin McCoy and Joseph VanAmberg
A fire extinguisher set off underwater creates a three phase (solid, liquid, gas) flow. Rising bubbles of the propellant are filled with clouds of powder.

Smoke Curls
