What you need
Use a sheet of paper and two stable, low supports, such as similar small boxes, on a tabletop. This is a miniature structure, not a weight-bearing object.

Make it
Use a sheet of paper and two stable, low supports, such as similar small boxes, on a tabletop. This is a miniature structure, not a weight-bearing object.
- 1
Place the supports a short distance apart and lay the flat paper across them.
- 2
Notice where it droops, then remove the paper and fold it into broad accordion ridges.
- 3
Place the folded sheet across the same gap and compare its shape.
- 4
Adjust the fold width or the gap once, changing only one thing at a time.
- 5
Choose the version you find most interesting, then put away the supports.
Short on energy? Try just one folded sheet across a very small gap.
A good place to stop: Comparing a flat sheet with a folded sheet completes the experiment.
Make it work for you: Use soft paper and broad folds. A helper can prepare folds if pressing is tiring.
Another route: Try a curved paper arch rather than an accordion, keeping the supports low.
