I have a puking witch punch bowl in need of a good recipe! I thought a green one would be appropriate. I found one with champagne in it, but given the number of people I will have I'm afraid this will end up too expensive. Any other ideas?
You could do Rainbow sherbet in Ginger Ale. I think that comes out greenish. You could also use lime instead of rainbow or add green food dye. You get a nice foam it as well which would be especially disgusting with the puking witch.
