The way your hand works: a mechanical hand project

I got my first Tinker Crate the other day!  I opened it up and I saw lots of fun stuff, like how a hand works and how to make a mechanical one.  It was very fun and I learned a lot about hands!  How often do you use your hands?  Most of the time, right?  Well, I’m even typing this with my hands and fingers.  Here are some pictures of my mechanical hand project from Kiwi Crate.
