Sugru: polymer clay that fixes and sticks to pretty much everything

Sugru is a soft modelling clay that dries in 30 minutes at room-temp to a waterproof, heat/cold-resistant, dishwasher safe, flexible semi-solid. It's self-adhesive and bonds with many metals, glass, ceramic, plastics, etc. It can be used to make or fix or remake things from shoes to spectacles to plumbing-pipe. I've just ordered some for home and office -- it comes in four colors and looks like it'd be hella useful, and at £7, I'm certainly willing to give it a try!
