Everyone has seen how paper sucks up water. The reason for this is its hygroscopic property. Paper has the ability to absorb and bind moisture from its surroundings. This changes the dimension of the paper sheet: when paper gets wet, it expands and when it dries, it contracts again.
We use this hygroscopic property to create movement mechanisms. To do this, one side of the paper must be sealed and the other side open or absorbent. In this tutorial we will explain how to seal the paper, how the direction of the paper is important for the bending process and show you some inspiring examples that you can easily copy at home.
