Columns, vertical structural elements that are strong in compression, are good at propping things up. In this video segment adapted from ZOOM, the cast uses paper cups to illustrate what makes columns strong and why they sometimes collapse. By fillin...g the cups with sand, they also show that even hollow columns of a weak material like paper can be made surprisingly strong. Closed captioning included. Run time 03:03.

The stone arch is one of the simplest and most elegant structures in architecture. But if an arch is built incorrectly, gravity can quickly cause it to crash into a heap. To prevent catastrophic collapses, architects came up with several tricks to ke...ep their arches standing, including buttresses, pointed arches, and pinnacles. In this interactive activity from NOVA, try your hand at constructing a stone arch and learn more about the physics behind it.
