Rain may seem a harmless nuisance to us humans, but for ants, it's a big deal. They can get trapped by just a single drop and risk drowning. Paradoxically, it's by mimicking liquids that ants manage to conquer them.
In the video above, Micah Streiff and his team from the Georgia Institute of Technology in Atlanta captured writhing groups of ants behaving just like liquids. Working as a group they can turn themselves into a "raft" as they seek dry land or travel down a surface following the same physical rules as a viscous liquid. Thankfully, they haven't been caught mimicking your morning coffee just yet.
