My daughter's coloring book has perforated pages, so you can easily rip out the pages for easier coloring action. Great.
Trouble is, the perforation isn't enough, and it's almost impossible to rip out the pages without tearing the paper. It is difficult to grab the paper near the perforation since it is so close to the binding of the book.
I remember having this problem as a child, too. Funny, you'd think after 30 years coloring book page perforation would be a "solved problem".
I have found myself sometimes the tearing the page at a shallow angle as possible helps, but other times not, and sometimes a sharp angle works, and sometimes not.
I'm wondering if there is any optimal angle or other technique to tear the paper, to maximize the stress applied to the perforation while minimizing the stress on the surrounding area, as to not rip the paper. The goal here is something that takes the minimum amount of time and effort, and maximizing chances of a successful tear.
