When I brought out the spaghetti and marshmallows I think my children thought we were having some kind of weird and wonderful dinner, not building structures.
This is a great activity for children of most ages as you can tailor it to their understanding. I let my 2 year old just build whatever she wanted, and she had a great time working out how to put the spaghetti in the right places. With my 4 year old we were a bit more structured and tried to build a tower.
Older children can think carefully about which shapes are strong shapes and will support their structure the best.
How to build a marshmallow tower
Spaghetti ( uncooked! )
Snap the spaghetti into smaller pieces.
Push the ends of the spaghetti into the marshmallows to build different shapes for your tower.
We started with a cube but when we put weight (Pooh bear in our case) on, it started to lean very precariously to the right and one of the spaghetti vertical pieces snapped. We then discussed what we would do to make it stronger. We decided to add some diagonal pieces which seemed to do the trick.
We thought it would then be quite good fun to try lots of different shapes to see if we could break them. Straight lines and marshmallow corners tend to lead pretty much to triangles but we had a lot of fun with other shapes too.
Make it a game. Challenge friends or family to see who can build the tallest tower!
Try small and then giant marshmallows. Which are easiest to build with?
Stable structure secrets
Triangles are great for making a stable structure.
Consider where the centre of gravity is in your tower. A wide base helps with stability giving a centre of gravity low down and central.
