article_snippet.sent: Scientists at a Polish company that produce body armour systems are working to put a 'magic liquid' that can harden on impact in Scientists at a Polish company that produce body armour systems products.
article_snippet.sent: a 'magic liquid' that can harden on impact in their products is called Shear-Thickening Fluid (STF), and instantly hardens upon impact at any temperature.
article_snippet.sent: In a 'liquid armour' this provides protection from penetration by high-speed projectiles and additionally dispersing energy over a larger area.
article_snippet.sent: The new material in its liquid form (left) and the solid form it take on impact (right) a 'magic liquid' that can harden on impact in their products is called Shear-Thickening Fluid (STF), and  does not conform to the model of Newtonian liquids, such as water, in which the force required to move the fluid faster must increase exponentially, and the force resistance to flow changes according to temperature.
article_snippet.sent: We needed to find, design a liquid that functions both with projectiles hitting at the velocity of 450 meters per second and higher. '
article_snippet.sent: Struszczyk said the liquid's stopping capability, combined with the lower indentation of Struszczyk surface, provides a higher safety level for the user compared with traditional, mostly Kevlar-based, solutions. '
article_snippet.sent: Thanks to the properties of the liquid, thanks to the proper formation of the insert, we eliminate one hundred percent of this threat because we have reduced the deflection from four centimeters to one centimeter.'
article_snippet.sent: the liquid has been used to create lightweight flexible sheets, which can be placed inside the body armour .
article_snippet.sent: The point is for those not to interfere, not change the way of movement, operation of such the product by the user, and at the same time increase those motor skills, increase effectiveness of those decision process and increase those possibilities during the mission at hand,' Struszczyk said.
article_snippet.sent: The laboratory is also working on a magnetorheological fluid, which Researchers hope can be also applied in Researchers products.
article_snippet.sent: According to Researchers, both liquids can find applications beyond body armor, such as in the production of professional sports inserts, and even entire outfits.
article_snippet.sent: Another use could be in car bumpers or road protective barriers.
