title_body: My Guinness is mixing into my harp and not staying separated, any trouble shooting ideas?
upvoted_answer: Here are some troubleshooting tips I've found (source):
  
  
    Hold your pint glass at an angle, and fill just over halfway with Harp
    or Bass. 
    
    Rest the spoon upside down over the center of the glass, and pour the
    Draught Guinness over the spoon which will evenly disperse the flow
    and keep the Guinness from mixing -- the Guinness needs to be on the
    top. 
    
    Serve while the nitro is still cascading.
  
  
  If they're mixing, my guess is that the Guinness is not being poured carefully enough, so that would be where I'd start.
