For a bit of a craft project with a genuinely rewarding payoff, an empty shampoo bottle can become a simple bird feeder. Cut a couple of small openings along the sides, just large enough for birds to access the seed inside. Thread a piece of string or wire through the top for hanging, then fill it with a birdseed mix and hang it from a tree branch or balcony railing. It’s an easy way to bring a bit of birdlife into your garden using something that would otherwise be thrown away.
From the bathroom to the balcony, an empty shampoo bottle has a lot more life left in it than most of us give it credit for. A bit of cleaning, a few careful cuts, and it goes from waste to genuinely useful in less time than it takes to walk to the bin.
