paper bridge challenge

build a bridge from a single sheet of paper that spans a 20 cm gap and holds a small weight. fold, score, and test — then photograph each iteration.

materials

  • 3 sheets of A4 paper
  • ruler
  • scissors
  • two books of equal height
  • small weight (e.g. apple or battery pack)

instructions

  1. 1

    set two books 20 cm apart on a flat surface — this is your gap

  2. 2

    using one sheet of paper (no tape or glue), try to bridge the gap so the paper holds the weight

    hint: folding creates strength — accordion folds, tubes, and corrugation all work

  3. 3

    photograph your first attempt before testing it

  4. 4

    place the weight in the centre — does it hold? if not, observe where it fails

  5. 5

    try again with a new sheet — change your folding strategy based on what you learned

  6. 6

    photograph your strongest design from the side so the fold structure is visible
