Votons !

OK, c'est en anglais, mais quand même :

Voting has now opened for the Google Science Fair Voter's Choice award. Between now and September 14, the public can cast a vote on the website for one of our 15 Global Finalist projects, that they think has the greatest potential to change the world. The winner will be announced during the awards show later this month.
