Tie household metal objects — old spoons, keys, washers, bottle caps — onto a length of string, and hang several from a stick or coat hanger. Hang the finished chime somewhere outside and listen to how the wind changes the sound depending on how hard it blows.
What you need
- string
- a stick or coat hanger
- old metal objects (spoons, keys, washers, bottle caps)
How to do it
- 1Tie a piece of string to each object, leaving enough length to hang and swing freely.
- 2Tie the other end of each string to the stick or hanger, spacing the objects so they can knock together.
- 3"Give it a shake and listen — which one makes the loudest sound?" Test before hanging it up.
- 4Hang the finished chime outside somewhere it can catch the wind, and check back on it over the next few days.
Variations
- If there's no outdoor spot to hang it: an open window works, or hold it near a fan indoors to test the sound.
- How it ends: listening to it catch its first real gust of wind is the natural payoff — that's the finish line, not the tying.
💡 Parent tip
Let them choose which objects go on it, even the mismatched ones — the resulting sound is more interesting with variety.
What your child develops
- Acoustics — different metals and sizes produce genuinely different pitches, discoverable by ear
- Fine motor skill — tying knots securely enough to hold weight
- Delayed gratification — the chime keeps working and sounding different for days after it's built
Safety notes
- Sharp objects like old keys can have rough edges — check for sharp points before handing them over. Supervise knot-tying for younger children.
