Why Buildings Don’t Fall Down

What is the strongest shape?  How did the Romans build structures 2000 years ago that are still being used today?  Can you really stand on eggs?  Can you build a bridge out of balloons?  What is a truss?  We use a ten foot truss bridge, a suspension bridge, a large block arch, slides, juggling, balloon tying, blues harmonica, and other props to demonstrate basic building principles.
