lazenby asks: Have you seen these guys? http://web.mit.edu/hml/ncfmf.html Yes, absolutely! Those videos, which date from the 1960s, are so useful that they’re still shown to undergraduates today. (Or at least Keep reading

Microfluidics
The field of microfluidics–where fluids are constrained to the sub-millimeter scale–is increasingly important in fields like chemistry, molecular biology, and microtechnology. At the microscale, surface tension often has greater effects Keep reading
Flow Visualization
This video, created by undergraduates as part of a fluid dynamics laboratory course, shows flow visualization of a von Karman vortex street in the wake of a cylinder in comparison Keep reading
Wave Pool
This Japanese pool, lined with computer-controlled actuators, uses the principle of wave interference to create complex shapes at the center of the pool. While we may be more familiar with Keep reading
Fluidized Sand
What’s shown in this video are some pretty spectacular demonstrations of fluidization, where a gas is introduced at the bottom of a bed of granular particles–like sand. At the critical Keep reading
Canon Sound Sculptures
In a new series of ads for Canon, colorful paints are placed on a speaker cone and filmed at high speed to create beautiful “sound sculptures”. Paint, like oobleck, is Keep reading
Steam Devils
The formation of the ethereal steam devil is quite similar to the formation of a fire tornado. In this case, the first frost of the season cooled air temperatures substantially Keep reading
Non-Newtonian Fluids
[original media no longer available] Non-Newtonian fluids have even made it into pop culture. #
Paper Plane Physics
[original media unavailable] It’s a little surprising that this would be so stable, but I don’t have any reason to believe it impossible. #
Wild Ferrofluid Shapes
In this fluid experiment, a ferrofluid–typically a liquid with a suspension of ferric particles–is exposed to rotating magnetic fields, which results in some wild shapes. #
