`` Metal that floats even if it sinks '' inspired by fire ants and squirrels is developed

Spiders and ants inspire metal that won't sink: NewsCenter
When you play the following movie, you can see how the metal is actually floating in the water with the new technology developed by the research group at the University of Rochester.
Two identical shaped metals can be put in the aquarium ...
One sinks quickly, while the other remains floating on the water.
Even if it is submerged with tweezers, it will float in a straight line.
Floating in the water is a bobbin- shaped metal plate with two thin aluminum plates aligned in parallel with a short gap. A 1-yen coin made of the same aluminum floats in the water, but the 1-yen coin floats because of the surface tension , so once it sinks, it cannot emerge.
The research group made hikari that floats in the water by making squid…
Inspired by the ability of the water
The SH surface treatment on the inside of the aluminum plate keeps the air tightly between the two plates, so even if it is submerged in the bottom of the aquarium with a weight ...
As soon as the weight disappears, it can rise to the surface of the water. How, even if it is submerged in water for several months, the ability to float is not impaired.
Moreover, even if you drill a hole, it will not sink.
At the time of writing the article, it takes 1 hour to process an area of 1 inch (about 2.54 cm), but if you use a laser with more than 7 times the output, the processing time can be significantly reduced That. In the future, the research group believes that this technology will be applied to ships, life jackets, and observation devices that can monitor the ocean over a long period of time.
