Attack of the robots!

This week's "Geeked Out" zeros in on the hottest tech videos making waves on the web today.

Robots have always captured the imagination. Lately, there have been many examples—including a cool clip that shows how 3-D printing technology led to the development of a spine-tingling spider robot made from 26 motors.

The Pentagon's Defense Advanced Research Projects Agency also recently unveiled its own scary robot, which looks like it's straight out of a science fiction movie. Known as Atlas, the robot is a 330-pound beast that may eventually be used for disaster relief, humanitarian aid and other missions.

Robots aren't the only things that have been clicking on the Web. An astronaut on the International Space Station recently demonstrated the art (and challenge) of hair-washing in zero gravity, while an intrepid scientist showed the world how waterbending isn't just something you see only in a Hollywood motion picture.

So who says science isn't fun (or cool)?
