The shape memory effect as demonstrated by the Ferris wheel. The wheel is made up of 10 springs stretched apart by weights. The video shows what happens when the springs are heated.

as the springs contract more weight gets pulled unto the right side... the right side gets a little heavier. then gravity turns the wheel clockwise.

I understand heat makes springs contract.
But I dont understand why the wheel should rotate.
For example, why clockwise and non anti-clockwise?
