If you thought the Terminator 2: Judgment Day T-1000 robot that changed shape was a nightmare, your nightmares might become a reality.
Researchers have created a "terminator-like" liquid metal that has the ability to stretch horizontally and vertically, as well as shape, according to a new study.
The study published in Applied Materials & Interfaces shows how molten metals such as gallium mixed with nickel or iron are actually able to be manipulated with the help of magnets in various forms.
"In addition, the vertically elongated MLMD (magnetic liquid metal droplet) can move horizontally with its half body in the solution and the other half in the air. It resembles the essence of an upright walking amphibian," the researcher wrote in the study's abstract ,
This is not the first time that researchers have created a bendable metal. In previous experiments, certain metals that are liquid at room temperature, including the aforementioned gallium and other alloys, could only be stretched horizontally due to high surface tensions. They must also be immersed in water to avoid the formation of a paste.
But the researchers, including the lead author of the study, Liang Hu, added to the solution the iron and nickel as well as tin alloys that were immersed in hydrochloric acid reduced the surface tension.
From there they managed to "stretch the drop to almost four times its rest length" and to manipulate it with magnets.
The researchers also said the liquid metal showed conductivity and by connecting two electrodes, an LED bulb could be lit.

"MLMD represents a fundamental and promising platform for liquid metals to further develop free-space multi-freedom triggering and ultimately lead to dynamically reconfigurable smart and biomimetic soft robots, "the researchers wrote.
