Gramophone, phonograph, record player, radiogram… Today, the replaced player and even a computer, and instead of plates — laser discs. Well old records where?

Then raise her fingers over the edge in several places and twisted into a kind of socket. Until the material has cooled, it can be given any desired shape, not only flower pots, but, for example, vases.
