You Asked: How do you get a ship in a bottle? — Greg, Shreveport, La. Marshall Brain Answers: This is one of those “picture paints a thousand words” kind of situations. These two videos show you the process for getting a ship in a bottle. The basic idea: build a ship that folds small enough [...]

Coolest Stuff blogger and adventure editor Amanda Arnold wrote about the Nazca lines recently – a collection of drawings at the ground that you can only see from the air. These geoglyphs (some are geometric shapes, while others are figures such as a monkey or an astronaut) are a mystery to this day. Why were they created? What were they for?

While we still don’t have an answer to that, we do have a clue as to what happened to the Nazca people themselves.

The Nazca civilization produced art, pyramids and beautiful textiles, along with the Nazca lines. Cahuachi, the capital for a time, may have been the biggest mud city in the world. But the Nazca had disappeared by the time the Incan Empire rose to prominence, and our answer to why they vanished may rest on a tree, the huarango tree.

It isn’t too hard to successfully pull off a handshake or fist bump, but executing a crisp high five is another matter. Not only can hand-eye coordination fail, leaving high fivers swatting at air, but if you don’t slap hands at just the right spot, the auditory effect is lackluster. I, for one, have fallen prey to such pitiful high fives in the past – that is, until my brother-in-law passed along an invaluable tip for making a sharp, satisfying high five every time.

You Asked: Is a 27-foot boat safe enough for the ocean? — Gus, Arlington, Texas Marshall Brain Answers: It depends – do you want to row or sail? If you would like to row, there is a whole class of 23-foot row boats that people regularly use to cross the Atlantic ocean. Known as the [...]

For the last year, the government health care idea known as “the public option” has been the focus of intense discussion and debate. There has been so much debate, in fact, that the future of the whole idea is far from certain. The public option has been inserted into legislation, taken out, put back in, [...]

Europeans have a longstanding tradition of being really, really weird and really, really suspicious of other people.

Chuck and I just recorded a podcast on totem poles that should be out soon and in the article there’s section on totem pole myths, specifically that they were used to ward off and/or worship evil spirits. That would be incorrect: totem poles are instead akin to a very tall wooden family history. Think a bit further, though. Where would that myth have come from? Yes, that’s right, European settlers. (I wrote another post on how European suspicions created the idea of witches.)

How about cannibalism? There’s a guy named William Arens who posited in 1980 that there’s never been a culture that practiced cannibalism. Instead, it was suspicious rumor generated by early contact between Europeans and native tribes. It’s not entirely odd, if you think about it. All it takes is an explorer in the grips of awe and cynicism while meeting a previously-undiscovered group of humans noticing there happen to be a lot of piles of bones here or there. Instead of considering the possibility that the people practice funeral rites that don’t include burying their dead (true), the explorer concludes that they eat one another (false), high tails it out of there and goes to tell everybody else that the group practices cannibalism. Sadly, the image of bone-nosed natives cooking Bugs Bunny in a huge pot is not a caricature of a real thought, but a pretty accurate portrayal of how whites viewed unconverted tribes.
