Ever wonder how your Meccano stays together when it’s made up of so many pieces? It’s called stability. The pieces are assembled in a certain way and tightened to make the Meccano strong. If the pieces were put together a different way and not tightened, it would be unstable, and your Meccano would fall apart and come crashing down. The more stable something is, the higher you can build it. Let’s use toothpicks or dry spaghetti and marshmallows and try to build a skyscraper. But remember, if you eat the marshmallows, you won’t have any for your building.
Make a square base by connecting four marshmallows to the end of four toothpicks or dry spaghetti pieces.
Repeat what you just did to make a second square.
Connect the two squares together to create a cube. How stable is your cube?
Try adding more squares to the top of your box. The more stable it is, the higher you can build it. Try making different shapes. Are some more stable than others?
