Today using spaghetti and marshmallows we saw who could build the tallest tower.
You can build very large structures from squares and cubes, but they will be weak and will usually fall down quite easily. If you try to make a structure out of triangles and pyramids, it will be strong but you will use a lot of materials before the tower gets very tall! The best way to build a tall tower is to use both triangles and squares that way you can build big structures that are less wobbly. A diagonal piece of spaghetti put across a square turns a square into two triangles and makes it more rigid
