Looks like Play-Doh, acts like Super Glue. Sugru, a brightly colored silicone rubber, is the brainchild of designer Jane ni Dhulchaointigh, who worked with scientists for five years to develop a material soft enough to mold yet durable enough to fix or "hack" things so they work better. Sugru (Gaelic for play) sticks to everything from metal to fabric and can be used to craft an array of improvements — softer corners, grippier handles, more comfortable shoes, even more decorative glasses.
