Awesome! I want to go in that maze for Halloween in teams with walkie talkies.
Ants are amazing creatures
"the bridges slowly move away from their starting point, creating shortcuts and progressively lengthening by addition of new workers before stopping, suspended in mid air."
"The bridges stop moving when the increasing costs incurred by locking workers into the structure, outweigh the gain the colony gets from shortening their trail."
Basically, these fucking ants collectively know to dismantle the bridge once they sense the traffic has reached a low enough point.
This is just one of many things one of the world's most successful species can do. Plus, their wars are just awesome to watch
