I don't speak Polish, but I think I can figure out what's going on here. A couple of guys put up fliers for their new "demolition business" around town. Problem is, they don't know anything about demolition and just figured they could make a couple bucks breaking stuff in their spare time. Surprisingly enough, they get a job to take down an old brick wall. So they show up with their only piece of equipment: their mother's Opel.
Youtuber Spiritplumber devised a cheap and relatively-simple way to extend your cell phone's battery life. Recording video on smart phones is notorious for draining your juice and he claims this workaround can last a few hours with just a couple of bucks. Or you can go the less ugly but more expensive route and just pick up one of these guys.
