Tinkering is what happens when you try something you don't quite know how to do, guided by whim, imagination, and curiosity. When you tinker, there are no instructions, but there are also no failures, no right or wrong ways of doing things. It's about figuring out how how things work and reworking them.... Tinkering is, at it's most basic, a process that marries play and inquiry.
