A silk handkerchief is shown and rolled into a ball and placed into a glass. The glass is covered with another handkerchief. Suddenly the handkerchief that is inside the glass starts to rise upwards and is seen to be magically penetrating the handkerchief that is covering the glass!
When the silk that was inside the glass has finished penetrating the outer covering silk it is seen to be resting on top of the outer silk and no holes or other openings can be found.
After the silk in the glass has completely penetrated the other outer silk the glass is uncovered and is seen to be empty!
This is a vintage E-Z Magic item but can still be an effective mystery today.
Comes with the glass, required handkerchiefs, and instructions.
