Thin Blue Line

In honour of our hard working men and women in blue - thanks Skip - this cocktail's for you:

Thin Blue Line

1 part Vodka
1 part Triple sec
5 drops Blue curaçao

Pour in the triple sec then the vodka on top. Then, with a straw, add the blue curacao to create a thin blue line between the two layers.
