1 oz of Tequila
1/3 oz of Triple Sec
1/3 oz of Midori melon liqueur (or watermelon liqueur)
1/3 oz of blue curacao liqueur
All liqueurs are chilled. first add 1 oz. of tequila, then add 1/3 oz. of triple sec, then add 1/3 oz. of midori melon liqueur, then add 1/3 oz. of blue curacao. If all of the liquers are chilled, the shot will go from this nice blue, fades to green, into a nice yellow. eg plasma cutter.
