The Hang Son Doong Cave in Vietnam (that's a photo of it, above), is the largest cave in the world—and it's got some pretty epic proportions. The cave was recently surveyed at 2.5 miles long with some passages as wide as 300 feet and, in places, more than 600 feet high. Stunningly, that's enough space to fit an entire New York City block of 40-story buildings, according to National Geographic.

That means tourists are free to walk the tunnel and take in this stunning sight.

A bad mattress can ruin any chance of getting a good night's rest. That's why companies hire professional mattress jumpers to perfect their products. The jumping is the last step in the process of making a hand-made mattress and helps to compress the cotton batting.

And while it might sound like a fun way to make a living, professional mattress jumper Reuben Reynoso told SFGate, "It's work. It's not for everybody. There is a right way and a wrong way to do it."

It would take hours to enjoy a typical 12-course meal. And so if you haven't got the time, you could try and get your hands on the "All in One" 12-course meal in a can. The meal "includes" a cheese with sourdough bread; pickled Kobe beef with charred strawberry; ricotta ravioli with a soft egg yolk; shiitake mushroom topped with filled peppers; halibut poached in truffle butter in a coconut crepe; risotto foraged ramps, prosciutto, and fresh parmesan; French onion soup with fresh thyme and gruyere cheese; roast pork belly and celeriac root puree; pear ginger juice as a palate cleanser;  ribeye steak with grilled mustard greens; crack pie with milk ice cream on a vanilla tuile; and French canele with a malt barley and hazelnut latte.

There are very few people left in Centralia, Pennsylvania, and that's for a very good reason: The town has been on fire for more than 50 years. The strange situation started back in 1962 when a fire was purposefully set to burn out a landfill. Unfortunately, because the landfill had also been an old strip-mine pit which was connected to a series of coal-mile tunnels, the initial fire sparked a raging underground inferno.

The town was almost completely abandoned and was condemned by the Commonwealth of Pennsylvania in 1992. And since there's apparently enough coal in the tunnels to fuel the fire for another 250 years, it's unlikely that anyone will be moving back to Centralia any time soon.
