here are the stuff u need (don't know if u have those things all over the world .if u don't just experience with others)

1- blue curaçao or bols blue
2-2 little botles of pink flugel(a german drink)
3-sprite
you will not get real drunk of it because its kinda light and low alcahol
but it taste very nice and fresh and its looks like purple rain in your glass.
a nice cocktail 4 the lady's .

Equal parts Tequila, Rum, Vodka, Gin, Triple Sec, double part Chambord, then fill with Sour Mix.

Or, Rum, Blue Curacao, cherry juice, and fill with pineapple juice.

I prefer the Chambord.
