[BNM] Freerice - warning, productivity will drop below zero.

[Antony Jones]

This site is such a good idea, and it's completely addictive.

Basically you have to match up words with their definitions, each time
you get one right, your vocab level increases, and 20 grains of rice are
donated to the world hunger foundation(?)

The rice is paid for by the pay-per-acquisition advertising banners at
the bottom of the page (so turn adblock off!)
