Coachella is almost here, and it’s really cool how so many of our favorite brands such as H&M use it as a platform to test out some really creative marketing and advertising for us open-minded millennials. There’s one more Coachella-bound stunt you’ll definitely want to check out if you’re headed west this month.

According to Ad Week, everyone’s favorite drive-through, Sonic, has teamed up with super-creative celebrity chef Christina Flynn to make the first products designed specifically for Instagram, purchasable through Instagram. For one day only on April 16, those within a geo-tag range during Coachella will be able to order up one of these mad scientist-looking shakes and have it delivered.

The #squareshakes are just that — all square. The containers, the straws, even the cherry on top is a square, mimicking the square shape of an Instagram photo. They’ll come in Sonic’s premium Creamery flavors, such as Buttered Toffee, Bourbon Brown Sugar and Wildberry and Lavender, and all you have to do is click the “shop now” button that will appear in your feed if you’re standing in a certain area of Coachella.

The price for a tasty, refreshing milkshake? Just post a photo to your own Instagram account. It’s doubtful they’ll have any problems getting people to agree to that!

Show us your best milkshake creations on Instagram with the hashtag #iamcreative!
