There is a river in northern Minnesota that seems to... disappear. The Brule River becomes a waterfall that flows into what is called the Devil's Kettle, and is not seen again. Even scientists haven't cracked this mystery, though they've tried. Scientists have dumped dyes, ping pong balls, GPS trackers, and huge logs into the kettle with the expectation that they will pop up somewhere in Lake Superior. Strangely, none of the objects ever pop back up. According to geologists, what's happening here should not be possible-especially considering the kettle is made of rhyolite, a rock much harder than limestone.
