You can either fill your glasses with ice, or fill your cocktail shaker with ice, however the latter is strongly recommended as it will mix the alcohol while also cooling it.
Fill your shaker (ice in) with vodka, gin, tequila, rum, triple sec and lemon juice.
Shake it Up
Shake the cocktail shaker vigorously in order to mix all of the ingredients well.
Pour and Cola
Pour the contents of the shaker, ice and all into both glasses evenly. Top off the glasses with your favourite cola (Coke or Pepsi both work extremely well).
Garnish and Serve
Garnish your glasses with the lemon wedges and you are ready to enjoy your delicious and potent cocktail.
