Cut and connect drinking straws using small pieces of tape or bent pipe cleaner as joints, building up a freestanding structure — a tower, a cube, or a geometric shape of the builder's choosing. Test how tall or how tricky a shape can go before it loses its balance.
What you need
- drinking straws
- tape or pipe cleaners
- scissors
How to do it
- 1Cut a few straws into shorter lengths for variety, keeping some full-length.
- 2Join straw ends with small tape wraps or bent pipe cleaner pieces to form the first triangle or square shape.
- 3Build additional shapes and connect them into a taller, freestanding structure.
- 4Test stability by giving the base a gentle nudge — reinforce any joint that gives way.
Variations
- If cutting straws feels fiddly for younger hands: use full-length straws only and build a simpler, wider base structure instead.
- How it ends: measuring the final structure's height against a ruler or the child's hand-span gives a clean, countable result.
💡 Parent tip
Have them sketch the shape on paper first if they're old enough — comparing the plan to the finished build is its own small lesson in how ideas change once built.
What your child develops
- Structural engineering — comparing which joint shapes and structures hold their form under pressure
- Fine motor precision — cutting to length and securing small joints
- Planning ahead — sketching or picturing a shape before building it develops forward planning
Safety notes
- Supervise scissors use appropriate to the child's age and skill level.
