Electron whirlpools: Scientists witness electricity behaving like water
Researchers at MIT have observed "electron whirlpools" for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, electricity is made up of discreet particles, so one might expect that they would both flow in similar ways.
