title_body: Piece that goes screwed in my steam wand
upvoted_answer: Is it a wand with a single tip at the end?
  
  To get microfoam, you only have to produce a little foam at the start of steaming, a few light 'rips' of bubbles, then the rest of the time is spent whirling this into the milk. Keep the wand tip just below the milk and a little to the side while keeping the pitcher flat. This will create a whirlpool that helps mix everything else up. Hope this helps.
