Here is an old old spell you can use as a way to say farewell to the Solstice and make a wish for the coming twelve months. It's less dangerous than it seems, though care should always be taken.
Fill a shallow dish with raisins and pour a few spoonfuls of brandy over them. As you pour the brandy, say the following:
Put out the lights, then set the brandy on fire. While it is still going, snatch one of the raisins from the flames. As you put the raisin in your mouth, make a wish. It will be granted in the next twelve months.
When doing this with a group, each person gets just one raisin. when doing it alone, you can pull out 3 raisins and make three wishes.
