SQUARE TO CYLINDER - ENGLISH - 26MB.wmv

It is unbelievable but you can fold a 2-D paper square into a 3-D cylinder. First fold a "Z" shaped spring. Then fold the square into 8 equal parts and crease there diagonals. Holding the top and bottom edges and gently twist the paper and make it into a cylinder. The model gently transforms into a spiral staircase and makes a cylinder! http://www.arvindguptatoys.com/toys/no-cut,no-glue cylinder.html This work was supported by IUCAA and Tata Trust.
