I have an assignment for physics class in which I have to build a paper bridge. Requirements are that only 10 sheets of typing paper and elmer's glue can be used, the bridge has to weigh less than 75g, has to be less than 5mm in thickness, and has to span a space of 15cm. The lighter it is and the more it can hold, the better the grade. Also, nothing but the "road" can be within or attatched anything in the 15cm gap. All supports and things must be outside that. Any ideas or advice? Thanks in advance.

Look at a piece of corrugated cardboard. Two flat surfaces with a spaced filler between.
Use one sheet (or piece of sheet) of paper and accordion fold it in tiny folds (perhaps every 1/4 to 1/2 inch). Glue this to a flat sheet (if necessary one "ridge at a time"). You should end up with the beginnings of your roadbed. The other flat sheet can be glued almost all at once.
Experiment with small sections first to get the technique down and to determine how many you want to use (stacked and glued) since each will add weight, but will also allow a greater load.
You can probably use simple cylinders for the supports. Corrugated cylinders would add weight by provide much more support.
