Moldable silicone clay is an absolute game changer for DIY types and craft fanatics. It's basically a putty you mold into any shape, let dry, and it stays put, but is 100% flexible. I used to spend about $20 for a tiny pack of the leading brand of silicone clay called Sugru, but now I make my own with two ingredients.
This silicone clay is great for repairing bad wires, fixing broken glasses, making bumpers for your electronic devices, and so much more. In this page, I repaired my frayed iPhone charger and made a pen grip for my refrigerator.
