It’s probably not much good against the rain, but this handy bit of urban fieldcraft from YouTuber sumitsumit would be hard to beat for showing off your DIY-fu at the local hackerspace, coffeeshop, or school. Pretty much guaranteed to impress that attractive gentleman or lady in your engineering class. It takes about 20′ of rope, includes an adjustable shoulder-strap, and—I suspect—could probably be tied or untied in ten seconds or less with practice. I don’t want to spoil sumitsumit’s reveal, so I didn’t include a screen-cap, but you can scan forward to 4:20 to see the finished product. [via Boing Boing]
