When marketing a fake golf ball finder as a bomb detector kills people
When Baghdad bought tens of millions of dollars’ worth of British-made A.D.E. 651s, advertised as a foolproof bomb detector, the Iraqi government thought it would be saving countless lives. But the devices were laughable—based on a toy—and in the end have led to many deaths. Iraq is not the only country that has been fooled.

Google also played a similar role reinvigorating the browser market with Chrome.

Want. If they actually work that is.

Why BlackBerry was doomed and why Uber and Netflix are ascendant: they swap what's modular and what's owned and bundled to move closer to customers while pushing production and ownership costs onto others.
Netflix has a lot more in common with Uber and Airbnb than you might think: it all comes back to the Law of Conservation of Attractive Profits, a core principle of disruption

The US governed once sprayed San Francisco with an airborne germ that showed blood red, killing one.
The Nuremberg Code was drafted in 1947 following the appalling revelations of human experimentation committed in Nazi concentration camps. The overarching goal of the Code was to establish a set of rules for the ethical conduct of research using human subjects, guaranteeing that the rights and welfare of such participants would be protected. Two important …

That time a crazy plot went awry and a marvel of engineering bomb took our a large part of a Lake Tahoe casino.
 
Wow, I've been inside Harveys multiple times and never knew this fascinating bit of history: an extortion plot with a complicated bomb in 1980.

I wouldn't believe this if I saw it in a movie...
 
Kids, don't try this at home: it's almost certainly not a good idea. But for those of you who are interested in physics, note several important points:

(1) The rocket fires under water: that works because it's a true rocket, carrying both fuel and oxidizer on board and not using air at all. The shape of the nozzle is also important, since water has an amazing ability to absorb heat and thus quench combustion; a caul around the nozzle keeps the water from getting at the ignition point from the sides.

(2) The primary explosion creates a roughly circular set of cracks. Those lead to "big" cracks opening up in the ice, as existing seams and weaknesses get expanded. 

(3) Note that the circular cracks become hexagonal (matching the big cracks) as you move outwards. What's happening is that the inner cracks happen first, and then those start the big cracks, which actually spread faster than the round ones, basically moving at the speed of sound in ice. By the time the last round cracks are forming, they're forming in ice that already has hexagonal cracks in it.

(4) Water is an incompressible fluid, which means that the shock waves are going to hit things under water very, very hard. This is likely to be lethal to anything underwater and nearby, and is how dynamite fishing works. The reasons why that's a terrible idea (and is therefore illegal nearly everywhere) are hopefully obvious.

(5) That said, watching things explode underwater is pretty cool.
