Using a piece of magnet, researchers have designed a simple system that can control the movement of a small puddle of water, even when it’s upside down. The new liquid manipulation strategy, described in the journal Cell Reports Physical Science on June 3, can have a wide range of applications including cleaning hard-to-reach environments or delivering small objects.
