Test flat and folded paper bridges with books and coins, record the results and change one thing for a second trial.
- Sketch a paper bridge — Set two books a hand-width apart. Draw a side view of your flat bridge and the folded design you will test.
- Load test log — Add identical coins one by one at the center. Write the last count held before the paper touches the table.
- Change one thing — Sketch your strongest design. Circle one fold or support you want to change, then build it again.
