Free Rice is a cool website. I played this word association game and was able to donate 500 grains of rice. One correct word equals 20 grains of rice. the website claims that 5,027,880 grains of rice donated yesterday.
Over 39 billion grains donated to date
Who pays for the donated rice?
"The rice is paid for by the sponsors whose names you see on the bottom of your vocabulary screen when you enter a correct answer. These sponsors support both learning (free vocabulary for everyone) and reducing hunger (free rice for the hungry). We thank these sponsors for their participation at FreeRice."
