Know the meaning of the word "lyophilization"? It means "freeze-drying," which I just discovered while taking the vocabulary quiz at FreeRice. I had to guess at it, but I guessed correctly, which means I caused 10 more grains of rice to be donated to needy people through the United Nations. Ads live at the bottom of the screen, and each successive click for a new vocabulary word generates the money to pay for the rice.
Ten grains... doesn't sound like a lot. But the challenging quiz is so addictive (at least for the editors in this office!) that you might wind up providing a lot of rice; the site started up less than a month ago, but (at this writing) 372,382,150 grains of rice have already been earned by players.
So go get smarter and feed someone, too.
