Stop throwing out old plastic water bottles. Here’s 10 brilliant hacks to use them around the house

Transform an old plastic water bottle into a self-watering system for your plants. Cut the bottle in half, fill the bottom half with water, and place the top half upside down inside it. Insert a piece of fabric or a cotton string through the bottle neck, allowing it to soak up water from the bottom half and deliver it to the soil. This simple system ensures your plants receive a steady supply of moisture, even when you’re away.
