In many ways, we center a large portion of our lives around festivals. They provide us days off from work, allow us time to be content with our families and loved ones, and a give us a chance to eat as much as we want without Aunt Carol saying something about our necks (it's thyroidal, Carol). However, some festivals are determined to push the needle to crazy. Here, for your consideration, are those offenders.

A couple months ago, the world was supposed to end. It didn't. But that didn't stop the Centers for Disease Control and Prevention (CDC) from warning citizens of one global possibility besides complete destruction—ZOMBIES.

As a kid, my favorite thing to do at the Natural History museum was a midday stop, when my family strolled past an antiquated looking vending machine in the museum's musty basement. The Mold-A-Rama machine was oddly shaped, George Jetson-esque, and spewed out made-to-order, brightly colored plastic dinosaurs. There was such joy in watching the liquid wax pour into the mold, and then eject a warm, custom toy—well worth the dollar or two demanded. A version of this tradition was recently elevat...

We love all things Jackass at WonderHowTo, but before Johnny Knoxville and his pals were sticking fireworks up their butts, snorting wasabi, and taking a shock to the gonads (à la the childhood game, Operation), in the far off land of Ontario, Canada reigned another daredevil—a man named Ralph Zavadil, a.k.a. Cap’n Video. Just as we all winced when Knoxville tore his uretha, community access viewers of the '90s cringed as Cap'n Video bounced off concrete and broke his neck... until Zavadil wa...
As someone who’s entering a time of life that involves weddings, reunions, and generally running into people I haven’t seen in awhile, I find myself being shocked by how much people have changed over the years. A lot of times, people will have dropped a bunch of weight, or have turned into a kind and articulate human being, or have obviously stopped doing so many drugs. It’s important, when complimenting people on positive life changes, to let them know how well you think they’re doing withou...

I have found that I get more specific results, with great pictures and detailed instructions. As a “mommy” blogger myself, I know that the majority of bloggers w...
The Writers at io9.com have been running through a fantastic series of blog posts, in which they're teaching their readers about the history of great 80s sci-fi and fantasy.
