Imagine someone following these directions carefully:
Pour the juice into a 5-gallon container. Boil the water and sugar together until the sugar dissolves. Set aside to cool, then add the grape juice and yeast package. Securely close the container so that no air is released. Allow the wine to ferment for four weeks before bottling.

They just need to add one thing.
After about four or five days, you should hear a loud pop from the room where the bucket was. The lid will probably be about 10-15 feet away from the bucket, and the walls and ceiling should be purple in color.
