Free Rice
Everyone likes helping other people, especially if it doesn’t involve too much effort. Free Rice has a rather unique and fun approach to help the World Food Programme. Now you can help people while you improve (or better, show off your awesome) vocabulary.
The website shows you a word with four optional answers. Simply click on the right answer and if you’re right, you have automatically donated 10 grains of rice. Get another word right and donate 10 grains more. The actual donations are done through sponsors that are shown on the website. Since October 7th (the launch date), 1,712,371,750 grains have been donated already.
What a great concept! Can’t wait to see more websites like this!
