Challenge: Dental Floss Bridge

You will be given paper and pencils, drinking straws, duct tape, dental floss, large paper clips, and pennies or zinc washers. Set up your bridge in the testing spot! Make sure you have a sweatshirt, cardboard or something soft on the ground under your cup. Start placing washers in the cup of your bridge! When the cup collapses, count your washers! Whose bridge held the most?
