Have you changed the lock and left the key idle? Do not rush to throw away such a seemingly useless thing as a key to a non-existent lock, because if you collect several such keys, you can make wind chimes out of them.
Of course, wind chime from old keys is not a very useful thing, but the process of creativity, especially if you involve children in it, will be very exciting.
To make the wind chime with your own hands, several keys of different sizes, multi-colored threads (not the thinnest, for example iris or acrylic threads for knitting, woolen threads are also suitable), multi-colored paints, a tree branch or a wooden plank (you can also take a stick from a Chinese set of sticks for food), scissors.
extremely simple. As you can see in the photo, you just need to hang the keys on strings in a row on a wooden stick. However, the craft will be brighter if you paint the keys with oil paint (you can also use nail polish or other paint that adheres well to a metal surface). You can also tint the stick with paints, wind multi-colored threads on it.
Tie a long string around the edges of the stick to hang the chime from a tree in your garden or home.
Before tying the thread with the key to the wooden stick, string a few bright plastic or wooden beads on the thread.
By the way, if you have a lot of keys, it is not necessary to place them on the same level tightly to each other. Hang them, for example, in a zigzag - making the hanging threads shorter or longer.
