Sugru is a brightly, colored, self-adhesive, silicone rubber bonding compound that cures overnight at room temperature to form permanent bonds. It has been fabricated by Jane ni Dhulchaointigh, who worked with scientists for five years to develop this material soft enough to mold yet durable enough to fix or “hack” things so they work better.
“I was making things with silicone sealants and sawdust, and started using the leftovers around the house,” she says at her east London base. “I modified a knife handle to make it more comfortable. My boyfriend said, ‘Imagine if everyone could do that — like with stiff jam-jar lids.’ It was a great idea.” But it took seven years, two experts and the materials department at Queen Mary, University of London, to create a silicone that would be sticky but would also set rock hard without heating.
