For the first time, researchers in France and Israel have observed how an emulsified liquid droplet can transform from a hexagon into a six-pointed star shape in response to rising temperature.

Eli Sloutskin and Alexander Butenko watched this droplet transform as they lowered and then raised its temperature. As it cools, the spherical droplet of hexadecane briefly becomes an icosahedron ...

Reversible temperature-controlled transformation of a microscopic liquid droplet from a sphere to a hexagon, to a six-pointed star, and back. The droplet’s volume is several picoliters. Disclaimer: ...
