Sometimes a droplet needs a little protection while it’s traveling to its destination. When that’s the case, we often try to encapsulate it in a layer of material that won’t Keep reading

Rifts in Rafts
A raft of particles floating on water has some natural cohesion from particle attraction and capillary action. But when the raft is pulled apart, what happens? Does it break cleanly Keep reading
Mimicking Asteroids
In nature, objects like asteroids, black holes, and atomic nuclei can get distorted when spinning rapidly. Researchers are exploring these objects using a new model platform: particle rafts levitated by Keep reading
Morphing Particle Rafts
A layer of tiny glass beads sitting atop a pool of castor oil becomes a morphing surface in this video. Applying an electric field creates enough electrostatic force to draw Keep reading
Breaking Up Granular Rafts
Particles at a fluid interface will often gather into a collection known as a granular raft. The geometry of the interface where it meets individual particles, combined with the surface Keep reading
