Apple Power Supply fraying
It's well-known that all apple power supplies and cables for the last 10 or more years fray and break after a few years of folding. This post shows you a simple way to fix them rather than buy a new power supply. 1. Trim off the excess plastic around the frayed cable 2. Join the frayed wires again with either new wire or tin foil 3. Take a straw; cut off a piece about 5cm, and cut it lengthwise. 4. Fill it with silicone sealant. 5. Open it and clip it around the frayed section. 6. Let it set before using it, e.g. for a day.
