Grab a large electric blender and place the ice cubes or crushed ice in it according to your requirement.
Pour 6 fluid ounce of tequila, 4.5 fluid ounce of blue curacao, 7.5 ounces of orange juice, 6 fluid ounce of pineapple juice and 3 fluid ounce of lemon juice into the jar of the blender.
Set the blender at low speed and blend the ingredients for 10 to 15 minutes or until all the liquors mix well and are smooth.
Arrange six cocktail glasses in the serving tray, place one or two ice cubes in each of them and pour the Cactus Jack Cocktail into them, dividing equally.
Garnish your drinks with any of your favorite fresh fruit wedges like lemons, limes, strawberries, cherries etc.
Serve the Cactus Jack Cocktails immediately before they lose their fizziness and taste.
