creativity is a gift

Have a read of this:
"The Mother of Invention"

Although the whole article is quite interesting, this excerpt is probably the most random and kind of amusing:

"I recently got a call from somebody in Defence," she reveals. "Very top secret, very hush-hush. Couldn't tell me their name. They asked, 'Is it possible to shoot bullets through your product? And can it be used to build walls around structures, like army deposits for instance?'."

She begins to get animated, jigging around excitedly in her seat, her big, silver, guitar earrings swinging wildly about her head. "So I started Googling because I love a challenge and I started getting info, like how much water it takes to stop a bullet. According to New Scientist, three centimetres of water will stop a 50-calibre bullet significantly, due to the surface area and the drag. So if you line up the Hogs and surround a structure then, yes, they do become bulletproof."

I never thought about stopping bullets with water! I mean, now that the idea has been shown to me, it makes a lot of sense.. although I suppose it's not really possible to wear bulletproof vests that have water in them..
