Yep, I learned that lesson the hard way in middle school. Came in under weight and it held the load fine when I had tested it on the deck, but the test in class put the load on the top and it crashed to the floor. It probably would have survived if it had been using popsicle sticks, but unfortunately the teacher decided that year that plastic straws were just as acceptable for the building material

It's quite amazing how much bend some of the bridges that passed the test had in them.
