The Bridge Challenge

After school one day this week, Trevor came home to a plain brown envelope marked "Challenge" on his place at the kitchen table. Pinned to the back of the envelope was an index card that read, "Build a bridge that can hold three Lego people at least six inches off the ground using only the materials in this envelope."

Inside the envelope was a stack of flimsy paper strips, paperclips, scotch tape, and a glue stick. The first two bridge attempts ended in frustration. You can see the span that finally worked in the photo -- it took about 45 minutes to finally win the challenge.

All that fun from a stack of paper strips leftover from trimming direction cards with a paper cutter.
