Molybdomancy (μόλυβδος in ancient Greek) is a technique of divination using molten metal. The method originates in ancient Greece and it is a common New Year tradition in the Nordic countries. Typically tin is dropped into water and the resulting shape is interpreted as an omen for the future. In Finland people melt small horseshoe-shaped bits of tin (uudenvuodentina) and then plung them into a bucket of cold water. However, the tin horseshoes commonly sold in Finland contain lead, and will soon be banned by the European Union. This is, therefore, the last New Year when this type of horseshoe will be sold in Finland.
