To make it into any shape —- you have to use a force.
So what a great way to show forces and at the same time have fun in making these
different shapes.
A BEND, A TWIST, A STRETCH - all forces. TENSION is a stretching force and also when
you hear that awful balloon noise as you twist it that is FRICTION.
