Switchblade has found this awesome website called Freerice which promises to donate 20 grains of rice for every vocabulary question you answer correctly.

All you have to do is guess a few synonyms, and for each correct answer you give, 10 grains of rice are donated through the United Nations World Food Program (WPF) to feed a hungry soul.
The money that pays for the rice comes from advertisements on the page.
Not only are they out to reduce the hunger thats there in the world, they are also increasing people’s vocabulary…which translates into some cool office timepass for me :)

To this day that has summed up to 580 million grains. See if you can help!
