It's like letting a kid loose in a candy shop for Dean. Most of the time he works on cars, but the reality is he's a pretty good mechanic as a whole and has the intelligence to learn when he wants to. And there's enough here that's already interesting him that he might have to get back to the library and find some books on all the different things here in the shop because he can already see himself building something, tinkering with other things. Because let's be real what else is he going to do in this place if there aren't ghosts or vampires, or demons to slay.

He slowly pulls his hand back though, at least waiting for an answer as he inches close to look at it more at least.
