Jane ni Dhulchaointigh has spent the last five years refining silicone technology to perfect her product, Sugru. It's a durable silicone rubber, that, in its early state, resembles fluorescent plasticine. It can be moulded into any shape and left overnight to harden. She is marketing it as a product that makes handles and grips more comfortable - inspired by a friend who broke her leg. Her friend used Sugro on the handle of her crutches to make holding them more comfortable, by moulding a grip to fit her own hand. "There's no other material like this," says Ms ni Dhulchaointigh. "It's a new silicone material that we invented and patented so that everybody could modify and improve things themselves."
