That's what I do. I think it's the first knuckle on the middle finger that pops... both when pressure is applied and when it is relieved. I can repeat it "ad nauseum" (especially for those around me!) So I don't think it's the fluid "cavitating" (the only thing that cavitates is my stomach... when I'm hungry) but perhaps a ligament being stretched and "popping" in and out of place. Can do it with both hands.
