Velcro is pretty handy stuff, but imagine if there was a soft, stretchy material with the same qualities. Well, now there is. Scientists from the University of California, San Diego have created a self-healing hydrogel that binds together in seconds, essentially copying the Velcro process at a molecular level. The new material could potentially find use in medical sutures, targeted drug delivery, industrial sealants and self-healing plastics.
A new material called Metaklett is like hook-and-loop (“Velcro”) made out of steel and much scarier. One side of the material bristles with sharp spikes and the other side has jagged steel brushes. Looking something like the mouth of a prehistoric shark, a square meter of Metaklett can support up to 35 metric tons and withstand heat of up to 800 degrees Celsius. Developed at the Technical University of Munich, Germany, researchers borrowed from the traditional hook-and-loop concept to design a fastener for extreme loads and environments such as automotive, building, or military applications.

A new product designed to open a slow-running drain caught our eye over the holiday period - a velcro-tipped, disposable drain snake called FlexiSnake
