    Bridges
    By John Vose

    You can get a box of 1500 plastic drinking straws from Sam's Club. They can be hooked together with masking tape. The surface of the bridge can be made/covered with paper or cardboard.

    Give them the requirements for distance to be spanned, width of bridge, etc. Have a competition for the bridge that will bear the most weight or specify a weight to be borne and have them compete to make the bridge with the fewest straws.
