Instructions
Hold one side of the yo-yo firmly in one hand while using the other hand to turn the second side counter-clockwise. Continue this until the two sides come apart. Place them on a flat surface.
Remove any existing friction stickers from both sides. Peel these off with your finger, or use an object that allows you to scrape the sticker off effectively.
Remove the backing from a new friction sticker.
Place the new friction sticker in approximately the same position as the old one. There should be a slight depression in the yo-yo where the friction sticker goes.
Press the sticker to secure it firmly against the yo-yo.
Screw the yo-yo back together.
