Flexibility

P.S. I know this comic isn’t very funny, but it was a tiring day at school, and I stayed up to midnight last night to write the last comic, so please forgive me if it’s not to your standards.

Flexibility is easier to explain than most of the other parts of diversity, which is kind of a relief to me, because I still have Strength and Hardness to cover on before the exam on Wednesday.

So flexibility is how much you can bend something without it cracking, basically. The more something can bend without cracking, the more flexible it is. Rubber and Nylon are very flexible, while construction materials like wood and metal are not very flexible. A common misconception is that as long as something can’t crack means that it is flexible. For example, can you try to bend a brick with your hands alone? Probably not. But does that mean that it is flexible? Of course not. Flexibility concentrates on whether a material is bendable. If you had a very thin sheet of whatever bricks are made of, and tried to crack it, you will find that it would crack easily without any effort.

To test whether something is flexible, cut a thin strip of whatever material you want to test and see if you can bend it without breaking it. Keep trying with lots of materials and you will find that most minerals and rocks are extremely inflexible.

By the way, skin happens to be greatly flexible. If you were to remove everything inside your body (bones, blood, heart, etc.), you would get a rubbery outer layer, that flopped uselessly around.
