Plastic laundry detergent bottle is a perfect to make a watering can from it. You only need a drill and an utility knife to finish such project. In the result you’ll get a very cheap gardening gift.
Here is what you need to do. Drill plenty of holes in the cap. To allow air to flow into the bottle and keep the water free flowing, cut a hole near the cap in the handle – not to close to the cap, otherwise the water spills out there, too. You’re done! Reuse is better than recycle, right?
