Highlighterhttp://www.caneycreekmolds.net/index.php?action=gallery;sa=view;id=1421The moral of this story is when you have a clogged Yorker cap just replace it. I had this issue and tried cleaning out the cap and in turn it was no longer a dropper but it almost poured. This was the outcome but because of the nature of how it happened I couldn't reproduce it again exactly.
