Spaghetti tower
You will make a small tower and let go for ten seconds. Long spaghetti pieces look like useful beams, but they can bend and break under a load.
- Build
- Explorer
- About 20 minutes
Help needed: yes for setup, nearby supervision and clearing spills or loose pieces
What you need
- Dry spaghetti
- Marshmallows for joining
- A timer handled by someone
The rule
It must stand alone for 10 seconds.
How to do it
- Ask someone to select intact pieces and clear broken fragments.
- Join three pieces with marshmallows to form a small triangle.
- Add three short upright sides around the triangle.
- Connect their tops with another triangle.
- Add diagonal pieces between a top corner and a bottom corner.
- Let go while someone times ten seconds of standing.
Why it works
A rectangle made from loose joints can lean into a different shape without changing the side lengths much. A triangle cannot change that way unless a side bends or a joint moves. Diagonal pieces can therefore help a tower resist leaning. Real spaghetti is still flexible and breakable, and marshmallow joints can soften or twist. A wide base and short supported lengths reduce some of those problems. Your model tests both the pattern and its materials.
Make it harder
- Use a slightly narrower base.
- Add another level with short pieces.
- Reach the same height with one fewer diagonal.
Ask Taz
- Why does a diagonal help stop a tower leaning?
- Why do long spaghetti pieces bend?
- Why can a strong-looking joint still twist?
Before you start
A helper should stay nearby and remove broken fragments before handling continues. Keep building materials out of mouths and away from younger learners. Ask the learner to identify the first bend rather than simply start again. Ask at dinner: “Was the weakest part a piece of spaghetti or a join?”

Common questions
Do we need special equipment?
Use the household items listed above. Begin with a small attempt on a clear surface before trying any harder version. The listed time is an estimate, so leave room to rebuild or repeat without rushing.
What if the first attempt does not work?
Notice where the result first changed. Alter one feature, keep the rest similar and try again. An unsuccessful attempt can still give you a useful question.
Do we have to post the result?
No. You can show it to someone at home. Online sharing is optional and needs the permissions in the privacy line above.
