Learn these life hacks to save time, save effort, and skip the hassle. 1. Don't toss old t-shirts you don't wear. Place the pillow on the shirt, flip it right over, and smooth it out. Your pillowcase is done. 2. If your indoor AC unit is dripping, don't rush to get it fixed. Try this method. Insert the hose into a water bottle, then seal it with tape. Now squeeze the bottle quickly. The gunk inside the AC will flow right out, then it won't leak water anymore. 3. Find a branch and shave it into a cone shape. Drive it into the pipe fitting, then screw one screw into each side. This makes it expand and grip the inner wall. Drill a hole in the handle, then just insert the wrench. Turn it counterclockwise to remove the rusted broken threads inside the fitting. 4. Add iodine and a scoop of laundry detergent to water, then stir it up. Soak dirty socks in it and scrub them clean and white. Number 5. Cut a rectangular hole in the middle of a piece of rubber tubing, then fold it in half. It fits right over pliers with missing old handle covers. Number 6. Mix laundry detergent, salt, and baking soda with 70-degree hot water. Pour it into the kitchen sink, bathroom sink, and floor drain to get rid of tiny flying bugs. Number 7. Cut a hole in the bottom of a plastic bottle and fit it onto the oil jug. This keeps oil from spilling everywhere when you add it to equipment. Number 8. Mix toothpaste and dish soap evenly. Dip a melamine sponge in it and scrub the sink and faucet. They'll shine like a mirror. Did you learn it?
