But let's not dwell on the negative.
So anyway, this week's challenge is: how would you make Batman's grapple gun? Would you make it gas powered, spring powered, motor powered, or something else? And how would you make the ending attachment? A magnet, a hook, or something else?
It's late, so I'll tell you how I'd do it tomorrow.
Also, I've decided something. I'm going to change these challenges to simply be every week, rather than specifically every Tuesday.
Update: I would use really really powerful motors, like how I'm making my web shooters (except considerably more powerful). I'd have the attachment on the end be an electromagnet, like in Christopher Nolan's films.
