I'm trying to build a bridge but I have no clue where to start. I need to make a poster first but I don't know which design to use. I have found a website with the exact same project I need to make. For all the details, please go to www.gravitykills.net. It has to be made of paper, hold 105 kg, and weigh no more than 125 g. What I'm trying to do now is select a design and make a poster. The instructions for the poster are on that website.
