April 2013: How It Works
For our annual How It Works issue, we break down everything from the massive Falcon Heavy rocket to a tiny DNA sequencer that connects to a USB port. We also take a look at an ambitious plan for faster-than-light travel and dive into the billion-dollar science of dog food.
Plus the latest Legos, Cadillac's plug-in hybrid, a tractor built for the apocalypse, and more.

Am I the only one who's irritated by the persistent use of "he" and "his" in the product descriptions? Is "they" so hard to use?
A couple of these are silly -- I won't say which.
Also:
Motion detector light switches are pretty old hat.
As for the B&D drill, I'd think that might be an awkward feature in tight spots
I can think of multiple reasons why I would not pay $300 for this automated gutter cleaner. The fact it would have to be manually moved from gutter to gutter, and still needing to climb up to each gutter are the primary reasons. There are much less expensive alternatives, and some work from the ground. Now if it were a complete system which could cover all the gutters of a home, and stay in the gutters year round, parking at the high end when not in use, maybe.
Interesting idea on the Gyro Screwdriver, but it would look more modern with a Philips bit. Who even uses slot-head screws anymore?
@Kokopure:
"He" is the grammatically correct pronoun to use when a person's gender is unknown. Stop being such a feminist.
