Magical sparkles

I was out the other night drinking John Martyns. 

White rum (2 parts)

Triple sec (1 part)

OJ (2 parts) 

Top off with ginger ale

Serve on ice

Amazingly, they'd never heard of them in the bar. So I told them how and they made it perfectly. 

Except for the glass obviously. And the magical sparkly things that appeared around it.
