My milkshake brings all the boys to Instagram? Kelis might have to tweak her lyrics for this Sonic campaign. The brand created a food just for Instagram... and that's also the only way it can be bought. Sonic #SquareShakes were developed along with Instagram personality @ChefJacquesLaMerde. The Sonic Square Shake comes with a square straw and will be entirely square, ideal for photographing. The shakes will be available via "Shop Now" sponsored ads on Instagram to Coachella attendees at the Base Camp festival grounds on April 16. Through the geo-targeted ads, festival-goers can order the shakes and sample them on the spot. Check out an intro video here and a site that explains the concept and curates photos. Goodby Silverstein & Partners created the campaign.
