Ancient Shadoof Counterweighted Irrigation Well
An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 12.
Materials Needed
- • Forked wooden branch (approx. 60 cm tall) (1 branch)
- • Straight lever pole (approx. 1.5 meters long) (1 pole)
- • Heavy stone (counterweight, approx. 1 kg) (1 stone)
- • Small tin can or plastic cup with string handle (1 unit)
- • Strong twine or paracord (3 meters)
- • Water basin or bucket (1 unit)
Pro Tips
- → The Shadoof is a first-century Egyptian invention that made lifting heavy water buckets effortless using counterweights.
- → Pivot a long pole in a forked upright branch: attach a heavy rock to the short end, and a string-bucket to the long end.
- → The rock counterweight lifts the heavy water bucket out of the well automatically, requiring hand effort only to pull the empty bucket down.
Safety First
Secure the stone counterweight firmly with duct tape and rope so it cannot slip loose during swings.

Step-by-Step Instructions
Step 1
Plant a sturdy forked tree branch upright in the ground (or lash a tripod of sticks) to serve as the pivot fulcrum.
Step 2
Rest a 1.5-meter straight pole in the fork and lash it loosely with cord so it swivels up and down.
Step 3
Tie a heavy stone to the short end of the lever and tie a small bucket on a string to the long end.
Step 4
Pull the bucket down into a water basin, let the counterweight lift the full bucket up, and dump it into an elevated canal.
