Making Magnetic Crystals From Ferrofluids

Ferrofluids are a great platform for exploring liquids and magnetism. Here, researchers trap ferrofluid droplets along an oil-water meniscus and then apply a magnetic field that makes the drops repel one another.  (Video and image credit: H. Khattak et al.) Read the full article

Growing Hydrogels in an Active Fluid

Active nematic fluids borrow their ingredients from biology. Using long, rigid microtubules and kinesin motor proteins capable of cross-linking between and "walking" along tubules, researchers create these complex flow patterns. (Video and image credit: G. Pau et al.) Read the full article

Kirigami Parachutes

To fly stably, parachutes need to deform and allow some air to pass through their canopy. In this video, researchers investigate kirigimi parachutes, inspired by a form of paper art that uses cuts to create three-dimensional shapes. (Video and image credit: D.

Bubbles Encased in Ice

If you've ever made ice in a freezer, you've probably noticed the streaks of frozen bubbles inside the ice. In its liquid state, water is good at dissolving various gases -- like the carbon dioxide in sparkling water. (Image credit: J. Meijer and D. Lohse; via GoSM) Read the full article
