This is a great vehicle to save themselves from catastrophic floods.
Vehicles that can assemble itself in 100 seconds and was able to keep
the thousands to millions of passengers safely as well as floating for
days, even up to several weeks.
A group of ants floating along the fire is a natural engineering. Scientists trying to figure out how the ants that creates a raft of safe and durable of their own bodies.
With the raft, they can save themselves from flooding in the original habitat of fire ants in South America, and migrate to a place far away.
The team of scientists led by Nathan Mlot, expert engineering of biology at Georgia Institute of Technology, United States, collecting fire ants on the edge of the road and filmed as well as freezing the ants it when they formed the Group buoyant. Once placed into the water in the laboratory, ball-shaped groups of ants were spread.
Ants clinging to each other, using the claws, jaws, and sticky pads on their feet, which released liquid oil, which makes them able to cling to the surface slippery. So that life raft, its shape resembles a cake so serabi.
The outer body of ants, called kutikel, hydrophobic or water repellent. The surface of the rough kutikel make ants can hold the air in her body when submerged in water and make up the lining of the plastron.
"A large group of fire ants that are holding it has higher water resistant, so that all members of the group can float and prevent water entering the raft," said Mlot.
A raft of ants that have benefited from a small body of ants. "On a scale of millimeters, the ants have great power, high speed, and ability to hold water when submerged air pockets, which ultimately makes a raft they antiair," said Mlot in the journal Proceedings of the National Academy of Sciences. "This ability seems to be missing on the larger size."
Alas, it's got a weakness of the raft of ants. Raft will be dispersed and sink when water was given a SOAP or other surfactants damage the surface tension of water.
