Give rice through trivia quizzes

Sadly, this doesn't involve getting rice for free. Happily, it does involve giving it for free. As you play vocab-building and other trivia games on www.freerice.com, rice is donated through the UN World Food Program. The revenue is generated through ads that appear with each correct answer, but these are easy enough to ignore. If you're feeling industrious you could even tape a long piece of paper across the bottom of your screen so you won't be distracted by these banner ads.


Effort involved: about as much as a grain of rice.
