Make It Real Batman Rappeling Hook

Hey guys, I'm the Hacksmith, and we just finished building a Batman grappling hook and rappelling device. Let's go test it out. So this is the auto-locking rappelling device that we designed and built. So in addition to being a grappling hook, it can also lock onto objects. Really hope this doesn't break. It's pretty strong. Let's do this. There we go. Oh, that's an icy edge.
