Free-standing structures from paper
Design & Technology · Key Stage 1 · The School
Flat paper is weak
Stand a flat sheet of paper on its edge. Rest a small book on top. It collapses at once. Flat paper bends far too easily to hold real weight up on its own. The shape is the problem.
Rolling it into a tube
Roll the same sheet of paper into a tight tube. Tape the edge so it holds its shape. Stand the tube on its end. Rest the same book on top. This time it holds. Same paper, only the shape changed.
Why a tube is stronger
A tube spreads a push all the way around its curve, so no single part takes all the weight. A flat sheet has no curve to spread the load. That difference alone explains why paper towel rolls stand up and flat paper never does.
Building a free-standing tower from paper alone
Use nothing but paper and tape. Roll four sheets into four tight tubes, taping each edge. Stand the four tubes upright, spaced out in a square. Tape a flat sheet across the top, resting on all four tubes, to make a roof. Test it: rest a small toy on the roof. It holds, because the weight travels straight down through the tubes, which are strong along their length, even though the flat roof piece alone would collapse instantly if tested on its own.
Shape over material
This one idea matters far beyond paper. Choosing the right SHAPE can matter just as much as choosing the right material. A weak material in a strong shape can beat a strong material in a weak shape. Remember that next time.
