I'm sure everyone is familiar with clogged dropper bottles ejecting a huge blob of paint when you squeeze too hard. Recently, I've been having a similar, more irritating problem. When I open a recently-shaken bottle, residual air pressure or something pushes out a mass of paint even when the bottle is upright. I pop off the tip to equalize air pressure, but that doesn't seem to help. Can anyone smarter than me suggest a solution?
