Water from a faucet impinges on the flat surface of a drain diverter, spreading outward into a hydraulic jet. It picks up a bit of chili oil, then travels circumferentially before sliding under the outward moving water.

Dry ice in cold water, viewed from above, produces only clear bubbles of CO2, without fog.

Three 1/2 inch steel balls heated to 700 F are dropped into water, showing film boiling. Video at 500 fps.

When a steel ball heated to 700 C is suddenly submerged in water, film boiling blasts an oxidized surface layer clean off.

Two 1/2 inch steel balls, heated to 700 F, bracket a room temperature ball as all three are dropped into water. The two heated balls show large wakes due to the Liedenfrost effect.

As a 700 F steel ball is quenched in water, the left photo shows the vapor jacket surrounding the ball, and the right image shows oxidized metal flaking off due to rapid cooling and contraction.

Bubbles erupt as air is blown downward into water through a one inch diameter tube.

Edges between soap bubbles in a two-dimensional sheet form arcs.

Blue food dye fingers into olive oil in a Hele Shaw cell as the top plate is lifted, creating a pressure gradient towards the center.

Fluid in a thin layer between plexiglas sheets exhibits a fingering instability when the sheets are separated and air is drawn in. Also known as the Taylor-Saffman instability in a Hele Shaw cell.
