Umbrella Illusion classic

The magician opens up an umbrella and shows it from all sides. The umbrella is then closed and inserted into a tube, which is put down in a visible place without any exchange. Eight colourful squared silks then appear, or are simply picked up. The magician puts the silks in a bag. The bag is briefly shaken and the silks Change into an umbrella canopy in the process. When the magician takes the umbrella out of the tube and opens it, the colourful silks are hanging from the ribs instead of the umbrella canopy.
