Sugru is extremely versatile, there really is no limit to what you can do with it. Sugru makes everyday objects even easier to use. I had read about it and recently purchased a package of 12 packets of Sugru. The typical size of a Sugru packet is about 2 1/2". The actual size is probably around 2" long by 1" wide and about a quarter of an inch thick. Sugru is used as a "hacking" object where you can use it to modify an object that already exists and make it better. On their website they have many examples. For instance, I used it last night to repair a hook, which the curved part broke off. With Sugru, I picked off a bit of it, molded it into the shape that I had wanted (a hook) and then I placed it on the broken piece and let it cure. Once you let the piece of Sugru cure, it will turn into a hard piece of flexible silicone. The creators of Sugru claim that it can withstand a temperature range from -60°C to + 180°C. I haven't put it through temperatures of that nature yet, but so far I'm satisfied with the product. The only gripe I have with it, is that it has a 6 month shelf life. To prolong use, I followed their instructions and kept it in the fridge. When I finally used it, I just allowed the packet to get to room temperature, and then got to hacking.
