Back in 1942, the U.S. Navy conducted a potentially groundbreaking experiment in an effort

to turn one of its ships invisible.

And it went wrong, with disastrous consequences.

Or at least, that's how the story goes.

Indeed, throughout history, militaries around the world have secretly conducted all kinds

of crazy experiments, some real, some shrouded in conspiracy.

So from psychic soldiers to flying bears, let's investigate some of the craziest military

experiments ever, and get to the bottom of them.

The Second World War was reaching its height, but the Allies had just suffered

a catastrophic loss of ships at the hands of German U-boat submarines. To combat this,

the U.S. Navy allegedly enlisted world-famous physicist Albert Einstein. Why? To develop

super-advanced weapons and defense systems for them, of course.

The craziest of these by far was an invisibility cloak designed to hide U.S. ships from the enemy.

Now it wouldn't have been anything like the one Harry Potter owned.

Einstein theorized that by surrounding a ship with powerful electromagnetic

fields, it was possible to bend light around it, effectively making it invisible.
