It's not necessarily spilt wine. There's a part of the service where everyone dips their finger (usually the little finger) into their wine glass once as each plague is read out and then shakes the wine off the finger whereby it lands wherever it falls, which could be on one's book, but most commonly the table cloth, although some families have their wine glasses (these are miniture glasses) on little saucers where people shake the wine off into the saucer. The calling out of the plagues is great fun. Blood, Lice, Blain, Locust, Scurvy, and so on (I have invented some here).
