Combine ice, tequila, triple sec and 1 ¼ of ounce lime juice in a cocktail shaker.
Shake well for 20 seconds.
Strain into a coupe or martini glass (I swear, it looks so pretty!).
To make the Salt Air topping, combine water, 2 ounces of lime juice, Sucro and salt in a blender. Blend on high until bubbles form. Spoon mixture on top of the margarita.
