A fruity bit of tequila that's actually more fun before you drink it, due to the appearance that gives it its name.

Shake tequila and orange juice with ice until chilled, then strain into a Collins glass, also with ice at your discretion. Slowly pour in grenadine and allow it to settle at the bottom of the glass, then gently stir it until the boundary between juice and grenadine is slightly hazy, and serve. Stir fully before drinking.
