What Can Possibly Go Wrong Using a Garbage Can as a Cannon?

We've all heard lame Polish jokes. This video will rekindle your desire to come up with one, with the key word being 'kindle.'

These modern-day MacGyvers, who are in Poland, decided it would be fun to ignite a garbage can, transforming it from a waste receptacle to a cannon. Except this is the kind of cannon you'd expect to see working without a hitch in a cartoon. And even then you get the feeling kids watching it would be all like, "That's crazy. I wouldn't try that."

But these guys are not children. No, they're vigilantes waiting for their moment to save Warsaw. Amazingly, it doesn't look like anyone is hurt, which just means you know they're going to do this again until someone loses an eye...or an arm...or a head.
