Bottle production box

The Performer introduces a rectangular wooden box with a hole on top. He turns the box showing it on all its sides. He opens the back door and front door showing the inside to be completely empty. He then closes the both doors and makes a magical gesture. He reopens the front door and a bottle is seen to have appeared inside the box. He closes the door and lifts the bottle through the top hole and places on the table. The box is again shown empty by opening the back and front doors. The doors are closed. Front door is opened. Another bottle is seen inside. The bottle is brought out through the top hole and placed beside the first bottle. The magician continues making bottle s appear until five bottles have appeared from the empty box!
