A single droplet of water rests under a microscope, but this tiny sea is far from calm.
00:06
Thousands of squiggly white worms known as nematodes, or more specifically vinegar eels,
00:12
surge through the droplet, gathering at its center and running laps around its edges.
00:17
Scientists have discovered more than 25,000 species of nematodes living all over the world,
00:23
each of them with their own quirks.
00:25
And for the vinegar eels, that quirk is dancing.
00:28
Like birds or fish, vinegar eels travel in swarms.
00:33
When scientists watched these nematodes swim under the microscope,
00:36
they saw the eels move randomly around the droplet at first, but after an hour, a strange order emerged.
00:42
The eels started swimming in synchronous, moving in the same direction at the same time,
00:47
and even oscillating their bodies back and forth with the same rhythm.
00:51
Scientists don't know how or why vinegar eels swim this way, but they know they're a force to be reckoned with.
00:56
Once the nematodes started swimming in sync,
00:59
they exerted a force on the droplet that could move an object more than 100 times the weight of their bodies.
01:05
Now that is one funky flash mob.
01:09
This research was published January 10th in the journal Soft Matter.
