Sure, OK, but that is basically like repeatedly dropping a manhole cover from 3 inches above someone's back.

At least the plug's only at the end of the pipe.

At my parents' house last year, the pipe connecting the manhole to the actual sewer below the street was clogged. Which isn't so bad, unless nobody really notices it and the sewage just keeps collecting in the manhole. After pumping a good 1.5m³ of delicious sewage out into the nearby bushes (smells great at ~25°C), I went down into the underworld (again, great smell). Found the pipe in question and managed to insert a hose with backwards-firing jets into it, connected to a high-pressure washer. The bloody blockage was 6m into the pipe. Probably grease and fat from the kitchen sink, most of all. Anyway, half an hour of bumping into it over and over again finally cracked it.

Not the most pleasant experience. No cockroaches though, so there's that.

And then she went to say hello to magic portal, the manhole cover?

Sorry maatc its a dupe http://videosift.com/video/NEVER-Throw-A-Firecracker-Into-A-Manhole

This vid has a lot of comments on yt! Some of my favourites are:

• parque leptospirose (Leptospirosis park, like as in fun park, only not so much fun)
  
• Cadê a mãe dessas criaturas?É perigoso fazer isso! (Where is the mother of these creatures? It's dangerous to do that!)
  
• E do jeito que eu conheço os politicos brasileiros... não vou ficar surpreso quando oficializarem isso como transporte público. (And from the way I know Brazilian politicians... I will not be surprised when they formalise it as public transportation)
  

On the whole they are split between the sentiment of "oh let them be kids" and they shouldn't do it either from traffic, open manhole covers, or whatever. I admit that leptospirosis wasn't my first thought when I saw the vid, but it's a nasty disease and well worth avoiding, and since it is transmitted via animal urine I can see how it could be a risk. Many of the comments pointed out that risk, as well as typhoid and other bacterial infections. Others said they did it too and were fine

That's not just mesh. That's more like security bar fencing. My guess is someone well-meaning but without much mechanical intelligence thought it would be strong enough for cars to drive over, and better than an open hole, so they welded it to a cylinder that happened to fit and poof, instant manhole cover. Either way, that's an engineering *fail.
