Bridge construction zone

We've lost our table to eat by, at least until all the glue sets.

Our son's 3rd grade Academic Challenge group has been studying bridges.

This is there homework assignment.

It's made entirely from spaghetti, marshmallows and glue. Other optional materials were toothpicks, scotch tape and paperclips. It had to span 75cm and 15cm in width. It also had to support 3 matchbox cars...as you can see his supports more than that. They also had to keep track of the materials they used because each item had a $ value and the goal was to build a bridge to meet the requirements the least expensively. He's not done reinforcing it yet so we don't have a $ total yet.
