Trevor Beatty

Food dye exhibits the Rayliegh Taylor instability, forming toroidal vortex rings in a mirrored image.

Jennifer Milliken

Food dye follows the wake of a finger in milk.

Felix Levy

Food dye in milk.

Zachary Wehner

Soap reduces the surface tension of milk, driving a flow that mixes in food dye.
More information


Thomas Pohlman

Soap lowers the surface tension of milk in the center of a shallow dish, resulting in food dye being pulled towards the edges

Nikita Novik

Surface tension driven flow. Dish detergent dropped on food coloring in milk reduces local surface tension, which pulls the dye to the edges.
More information


Christopher Francklyn

Dish soap on a pool of food dye drops the surface tension of oobleck, which pulls the spread of the dye.

Hot and Cold Smoke from Flow Visualization @ CU Boulder on Vimeo.


Spencer Aguilar

Cigarette smoke is trapped under two glasses. The surface under the glass on the right was warmed, creating convection currents in the smoke.
More information


David Gagne

Smoke rises and spreads from a candle smothered by a glass.
More information


Jose Orozco

A buoyant plume of incese smoke forms a curl.

Elizabeth Crumb

Sparks fly up from a wood fire at 1 m/s.

Aaron Lieberman

Flaming WD-40 exits a glass bottle.

Hans Loewenheath

A 0.5 inch diameter droplet of honey slides down a wire at Re=40, exhibiting a classic raindrop shape.
More information


Gabriel Paez

Droplets of honey descend three strands of human hair slowly due to honey's high viscosity.

James Shefchik

A column of dilute milk is momentarily suspended after a child's toe was suddenly lifted from a pool.

Patrick Cotter

A large droplet transitions from film boiling to nucleate boiling, and the Liedenfrost effect is ended.

Matthew Bailey

A droplet of water falling into a shallow pool of water rebounds into a Worthington jet.
More information


Lindsey Yarnell

A droplet splashing into a shallow pool forms a crown shape while the surface reflects a diffraction pattern in the background.

Shea Zmerzlikar

Ball impacting milk.
More information


Zachary Brunson

A stream of mercury impacting a solid surface displays a hydraulic jump.
More information


Paul Sweazey

Laminar flow over a dam in a flume becomes turbulent on impact.
More information


Lotem Sella

Soap bubbles colored with food dye.
More information


Faith Batrack

Air comes out of solution as water cools to freezing. If frozen quickly, both large and small bubbles are formed. Pure water freezes first at the periphery, trapping bubbles in the interior.
More information


Ross Pitcairn

An aquarium 'airstone' generates an air jet, illuminated by red and blue LEDs.

When a water balloon is popped by a pellet gun, the contracting rubber skin and pressure drop disturbs the surface. The water seems to float momentarily before falling. Filmed at up to 1000 fps by a Casio EX-ZR100.

Daniel Allen

Guiness poured into a glass exhibits downward flow near the surface of the glass as bubbles rise in the center.

Gas Bubble Flow in Nitrogenated Beer from Flow Visualization @ CU Boulder on Vimeo.


Alex Meyer

When Guinness Draught Stout is poured into a glass with sloping sides, the bubbles formed by nitrogen and CO2 coming out of solution rush upward in the middle of the glass, and the liquid recircualtes downward near the walls, carrying small bubbles along.

Jonathan Severns

Phenol from a glow stick forms an emulsion in water when stirred.

Mark Carter

Air bubbles and magnetically excited ferrofluid suspended in liquid soap.
