What's more human than looking at a Roomba and saying "not having to vacuum is great, but why can't it bring me a beer?" With just a few slight modifications we now have that reality. While the robot revolution is inevitable, we might as well put our feet up and give the robots a half decent reason to revolt against their humiliation. What once was roomba has now become brewmba.

Here we were spending all of our waking hours setting our thousands and thousands of dominos up by hand. This is a godsend to anyone like us whose children go unfed due to the countless sleepless nights we spend setting up dominos. Our domino-chapped and blistered fingers have this guy to thank for creating a handy automatic domino machine.

Why anyone would go through the effort to re-engineer their 3D printer into a sandwich machine is beyond sense, until of course you see this baby in action. Obviously it would be faster, easier, cheaper and probably tastier to just make it by hand or just buy a sandwich, but then you wouldn't get to say you have a sandwich machine. In a sense, it's 3D printing a sandwich. Not actually, but definitely sort of! 

Explosive hydroforming is the process of using an explosion to shape metal. The pressure from the explosion in each one of these tanks violently and pretty much instantly turns them into spheres. It's kind of like magic, and it's very fun to watch.

Just because someone's being paid to do their job doesn't mean that they're not prone to moments of complete and helpless failure. Some failures are more impactful than others. This particular failtastrophe involves a power plant chimney falling across some wires and right on into some poor and unfortunate building storing transformers. 

So, usually in metalworking, you'd shape stuff by with a punch or a press. At least that's what Wikipedia says. Wikipedia also says that  hydroforming is the process of shaping metal using water pressure. For materials that are too strong or large for traditional hydroforming, one option is explosive forming, sometimes called explosive hydroforming. That's where the pressure used to shape metal comes from, you guessed it, an explosion. This ends our remedial knowledge of the complex processes involved with metalworking. Just watch the thing go bang.

Here are two machines, both capable of balancing themselves using the power of reaction wheels. First, it's kind of amazing that people do this every day without even thinking about it. Second, it's really amazing that someone figured out how to engineer self-balancing machines out of a few motors and strategically placed wheels. For some funny engineering, here's a dude who kicked up his video game rumble several notches.
