Use full-size marshmallows rather than the miniature kind. Using 2 strands of spaghetti instead of just 1 will strengthen your tower and help it to eventually stand upright. Push the spaghetti far enough into the marshmallows so that it feels stable, but not far enough to come through the opposite side. Around halfway will do. [2] X Research source
It might be tricky to push these next spaghetti strands into the same marshmallow. Do it carefully, and try to add the strands just next to where the first strands were pushed in.
Replace any broken strands of spaghetti with new strands.
Your square so far will look like a rigid “U” shape.
You should now have a completed square shape made out of 4 marshmallows and 8 strands of spaghetti.
Start with 9 squares if you are not sure how many to begin with. This will give you good practice in creating a smaller tower.
Each square will end up with 8 more spaghetti strands pointing upwards.
The marshmallow will connect the strands and hold them together in a point type shape.
If you began with 9 squares, you will end up with 9 pyramids in total.
Make sure that the base pyramids are close together to ensure that your tower is stable.
Be very careful to avoid leaning or placing pressure on the base pyramids.
You will notice your tower beginning to narrow in as it gets taller.
The bigger your tower, the longer it will take to reach the top.
Around 20 minutes is a good place to start for a competitive spaghetti tower match. You don’t have to compete with others. Try timing yourself, and see if you can build a better tower each time. You can judge the towers based on height or stability.
Have a measuring tape ready so that you can measure the end results.
With limited supplies, the design of the towers will need to vary. Get creative, and see how tall and stable you can make a tower with only 1 marshmallow.
