The magician is seen holding a white rose. He then takes and breaks the head of the rose off and turns it into a white silk streamer. Later in the routine, the magician takes and pours a glass of wine from a wine bottle. He then takes the broken rose stem and dips it into the glass of wine. Upon removing the stem from the glass of wine, the stem emerges with a beautiful red rose on the end.
Multitude of other ideas/routines can be performed with this ultility glass. You are only limited by your imagination.
