Ferrofluid Microlandscapes
Ferrofluids are an ever-fascinating topic. Consisting of ferromagnetic nanoparticles suspended in a carrier fluid, ferrofluids are known for their bizarre behaviors in the presence of a magnetic field, like their Keep reading
Fluids Round-up
Here’s to another fluids round-up, our look at some of the interesting fluids-related stories around the web: – Above is a music video by Roman Hill that relies on mixing and 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
Magnetic Putty
Sometimes fluids are slow-moving enough that it takes timelapse techniques to reveal the flow. Fog is one example, and, as seen above, magnetic silly putty is another. The putty is Keep reading
“Cymatics”
Nigel Stanford’s new “Cymatics” music video is full of stunning science-inspired visuals. The entire video is set up around various science demos–many of which will be familiar to readers–that translate Keep reading
“The Flow II”
“The Flow II” film by Bose Collins and colleagues features a ferrofluid, a magnetically-sensitive liquid made up of a carrier fluid like oil and many tiny, ferrous nanoparticles. Although ferrofluids Keep reading
Hydrophobia
On a recent trip to G.E., the Slow Mo Guys used their high-speed camera to capture some great footage of dyed water on a superhydrophobic surface. Upon impact, the water Keep reading
Fluctuating Ferrofluids
https://youtu.be/MU7wiveVCbg Ferrofluids–liquids seeded with magnetically sensitive ferrous nanoparticles–demonstrate some beautiful and bizarre behaviors when exposed to magnetic fields. This video shows the reaction of a pool of ferrofluid to the Keep reading
Ferrofluid Thrusters
Ferrofluids–magnetically-sensitive fluids made up of a carrier liquid and ferrous nanoparticles–may soon have a new application as a miniature thruster on nanosatellites. Microspray thrusters use tiny hollow needles to electrically Keep reading
