Lithium is a marvelous element. It is an alkali metal, and as of such, is highly reactive. It is relatively difficult to buy pure, but can be extracted from lithium batteries. First you must obtain some dead lithium batteries. This shouldn’t be too hard, as most people will readily give them away when they no longer produce a sufficient current. Fresh ones will work too, but it’s rather...

The Airbus A380 is a true wonder of modern engineering. It is the largest airliner ever made, with a carrying capability of up to 853 passengers. Being 50% wider than the Boeing 747, it’s closest competitor, the Airbus has truly surpassed all previous achievements of plane construction and interior design. A380′s level of comfort (well, at least for business-class passengers) is remarkable.... 

Outer space has always caught the imagination of people. The fascination is rooted in the inherent curiosity people have for the unknown.

Stairs are great and all, but they’re certainly not the most fun way to get down from the top floor of a building. I’m pretty sure that honor goes to slides. Which is why I really want to visit the Technische Universitat in Munich, Germany. Yes, this school features a couple of gigantic slides that help students get from the top floor to the ground-level patio in a matter of seconds. Why... 

It’s hard to imagine how much the world has changed in the past decade — but io9.com‘s infographic tells you the whole story. So, what’s changed?
