How to Make a Bamboo Man Kung Fu Toy
Baca versi Bahasa Indonesia: cara membuat mainan kungfu dari bambu
To make a bamboo man kung fu toy, cut a dry bamboo cane into eleven short sections — one neck, four torso, four arm and two leg pieces — sand every edge, then thread them onto string so the joints hang loose. A second cord passes through both arms and down through a slit in a table; pulling it from underneath is what throws the arms into their kung fu swings.
The toy is called zhujieren (竹节人) in Chinese, literally "bamboo-joint person". It is one of the cheapest toys ever invented — an offcut of bamboo and a piece of string — and it went viral online because of how expressive a completely mechanism-free object can be when you pull its strings. This guide covers the full build, the measurements that actually matter, and the three mistakes that make a first attempt flop.
We rebuilt the toy as a browser game with real rope physics — no bamboo, no saw, no waiting.

Materials
- Dry bamboo cane, 2–3 cm across, about 40 cm long
- Nylon cord or strong cotton string, about 1.5 m
- Two thin bamboo splints for the sticks
- A drop of wood glue
Tools
- Fine-tooth saw
- Hand drill with a small bit, or a heated awl
- Craft knife
- Sandpaper, ruler and pencil
Total cost is close to nothing if you have access to bamboo, and the whole build takes about ninety minutes for a first attempt. Most of that is sanding, which is also the part most people rush.
Step-by-Step Build
Choose and dry the bamboo
Pick a cane roughly 2 to 3 centimetres across. This is the one decision that quietly determines whether your toy survives: green bamboo keeps shrinking for weeks after you cut it, and as it shrinks every joint loosens and the string starts to rattle around. Use a cane that has already seasoned, and reject any piece with a crack running along its length.
Cut the eleven pieces
You need four torso sections of about 3 cm, four arm sections of about 3.5 cm, two leg sections of about 4 cm, and one shorter 2.5 cm piece for the neck. Mark them all before you start cutting. Saw slowly and rotate the cane as you go, so the rim shears cleanly instead of splintering out on the far side.
Sand every cut edge
Round off the inside and outside rim of all twenty-two cut ends. This feels like a chore and it is the single highest-value step in the whole build — an unsanded rim behaves like a blade against the cord and will saw through it within a few dozen matches. It also stops the joints from catching as they swing.
Drill the arm holes
Each arm section needs a hole passing straight through it, near one end, so the control cord can run across the piece rather than along it. Bamboo splits under pressure, so drill slowly with a small bit and let the tool do the work; a heated awl pushed through gently is a good low-tech alternative that seals the fibres as it goes.
Thread the spine and legs
Run the main cord down through the neck piece and the four torso sections in order. At the bottom, split the cord and take one strand down through each leg, knotting under each foot. Keep the whole spine loose — the figure should slump if you hold it up, because that looseness is what later reads as a flailing body.
Thread the control loop
Take a separate cord and pass it in through the outside of one arm, across the front of the chest, and out through the other arm. This one loop drives the entire toy. Leave both tails long for now; you will trim them only after tuning, and cutting early is the most common irreversible mistake.
Lash on the sticks
Bind a thin bamboo splint to each hand with a few turns of string and a drop of glue. Keep them light. A heavy stick feels more impressive in the hand and completely ruins the toy, because the extra mass damps the whip that makes the arms fly over the head.
Set up the table slot
The toy needs a gap to work. Traditionally that was the seam between two planks of a school desk; two boards laid a centimetre apart on any table do the same job. Stand the figure over the gap and drop both control tails through it so they hang underneath.
Tune the tension
Pull the two tails from below and watch. If the arms barely lift, the cord is too long — shorten it. If the whole figure hops off the table, it is too short. You are aiming for the point where a sharp tug throws both arms right over the head and they fall back on their own. Only when that feels right should you trim the tails and knot handles into them.
Three Mistakes That Ruin a First Build
Tight joints. Beginners thread the cord snugly because a loose figure looks unfinished on the table. It is exactly backwards: the toy has no mechanism, so every bit of its character comes from joints that overshoot and swing past where you expected. If your figure moves as one stiff piece, loosen everything by a couple of millimetres.
Cord that is too thick. A heavy cord binds in the drilled holes and turns a sharp tug into a slow lift. Use the thinnest string that will not break — thin nylon fishing line or waxed cotton both slide beautifully through bamboo.
Cutting the tails too early. Tuning is trial and error, and every adjustment shortens the cord. Leave twice as much as you think you need until the toy behaves, then trim.
How to Play With It
Stand the figure over the slot, hold one control tail in each hand under the table, and pull. Pull one side and that arm whips upward; alternate quickly and the figure appears to throw a combination. The traditional duel puts two figures over the same slot facing each other, with a small paper balloon tied to each head — the first player to burst the other's balloon wins. Some regional versions score knockdowns instead, where simply toppling the opposing figure ends the round.
If you want to feel the timing before you commit to sawing bamboo, the digital version on this site runs the same idea on real physics: two ropes, loose joints, and arms that overshoot exactly like the real thing.
The toy is sold commercially as "Bamboo Man Battle" and similar names, usually as a two-figure set with a slotted board included — handy if you want the duel without the woodwork.

FAQ
What kind of bamboo is best for a bamboo man toy?
A dry, seasoned cane roughly 2 to 3 centimetres across. Green bamboo shrinks and splits as it dries, which loosens every joint, so use a piece that has already dried for several weeks and has no lengthwise cracks.
How long does it take to make a bamboo man kung fu toy?
About an hour and a half for a first attempt, most of it spent sanding and drilling. The cutting takes ten minutes; the tuning at the end takes as long as you want to spend on it.
Can I make one without bamboo?
Yes. Paper straws, wooden beads, cut lengths of dowel and even rolled cardboard tubes all work, because the toy relies on loose joints and a control string rather than on the material itself. Bamboo simply gives the characteristic hollow knock.
Why do the arms not fly up when I pull the string?
Almost always the cord is too long or the holes are too tight. Shorten the loop so it is taut when the figure stands upright, and check that the string slides freely through each arm rather than binding on a rough edge.
Is this toy safe for children to make?
The finished toy is fine for children, but the build involves a saw, a knife and a drill, so an adult should handle the cutting and drilling. Bamboo splinters are sharp, which is why sanding every cut edge matters.
