This is a fun STEM challenge. Build a bridge that is at least two feet long using only 50 bamboo skewers and string. You can use any kind of string and any quantity. You can not use glue. You can cut the skewers or do anything you want to them. The bridge must support at 12 pound brick.
My daughter used waxed thread and created this bridge based on triangles. Triangles, as all three of my children have told me, are the strongest shape.
If you want to try this at home, here are the supplies:
10″ Natural Bamboo Skewer, 300 for $5.5o
Waxed thread, 1 spool $8.99
Here’s the challenge again but with spaghetti instead of skewers.

That turned out great! My boys made bridges using spaghetti, tape, and hot glue last year; it was quite the challenge.
