5 papers to make a tower can bear 250g
1) For the support of the tallest tower, I made the circle, because circles have the least surface area. (can reduce the use of paper)
2) To make a tower stable, I made a support. We should make a bigger bottom surface area.
Those skills are useful because we are the winners in building this tower (83cm).
HA! HA! HA!
