Manila folder bridge design

For last week me and my group were given the task of creating a bridge out of Manila folders and three feet of tape and our first design was two triangle being connect by rolled up pieces of Manila folder but then I came up with the idea to roll whole Manila folders and try and make a bridge out of it and after much experimentation we came up with our final design which broke the class record of 37 magazines and won the competition with holding a total of 49 magazines
