It’s the time of year when new Gallery of Fluid Motion videos start popping up online. We’ve already featured several and no doubt there will be more to come. Today’s Keep reading

Re-Entry
Atmospheric re-entry subjects vehicles to extreme conditions. At high Mach numbers, the leading shock wave compresses the air so strongly that it reaches temperatures hotter than the surface of the Keep reading
Visualizing Vortices
Flow visualization can be a valuable tool for understanding fluid dynamics. In this video, we see how it can help elucidate the mechanisms of flapping flight. By dyeing vortices from Keep reading
Nectar-Eating Bats
Nectar-eating bats have evolved to use several methods to drink. Some bats, like the Pallas’ long-tongued bat (top), use a lapping method. Hair-like papillae on the bat’s tongue increase the Keep reading
Glow-Stick Ferrofluids
Ferrofluids create all kinds of fascinating shapes when exposed to magnetic fields. In this video, Dianna from Physics Girl shows off what happens when you combine a ferrofluid with glowsticks Keep reading
Mammatus Clouds
Mammatus clouds, the bubble-shaped protrusions sometimes seen underneath cumulus clouds, are a rare and dramatic type of cloud. The mammatus is typically short-lived, with lobes lasting only 10 minutes or Keep reading
Bullet-Time Inferno
Remember the bullet time effect from The Matrix? This spectacular video gives you a similar effect with the turbulent flames created by firebreathers. To capture this level of detail, Mitch Martinez Keep reading
How Plants Move
Though most plants don’t move at speeds that we humans notice, many plants are remarkably active, as seen in the timelapse animations above. Much of this motion is driven by Keep reading
Extinguishing Flames
Putting out fires can be a difficult, water-intensive task. In this video, scientists demonstrate how using a non-Newtonian fluid can make it easier to extinguish and suppress flames. Where water Keep reading
Pollock-Style Physics
Here on FYFD, we like to show off the artistic side of fluid dynamics. But some researchers are actively studying how artists use fluid dynamics in their art. In this Keep reading
