Sorry, no cool project, but simply fridge magnets. We have some neodymium magnets on our fridge. They are so strong they are a bit difficult to remove, especially since they are chrome plated (and therefore have a very smooth surface). So, I used some Sugru to add a knob to each of them. But, why are you impressed, Steinar? I am impressed because I didn't degrease the magnets, and the Sugru still stuck properly. There aren't that many products which adhere well to a chromed surface with residue of skin oils.
