Free Rice

For every vocab question you get right, they donate rice to help end world hunger!
Some of these I don't even know, but I'm looking them up on dictionary.com :)

Good stuff! I "donated" about 730 grains of rice before I started to flag and grow bored.
It makes me wonder just how much of the rice is actually donated?
I'll have to try and investigate how this works. I imagine they use advertiser revenue, but... how can they estimate the grains of rice, for example?

They have a page on the site that lists how much has been donated.
