Friday at 8 p.m. Earth Onion, a women's improvisational theater group, will perform "Woman Potion" in Cabell Hall. The performance will be a series of skits narrated by a witch who creates a potion to "add to the understanding of women's dilemmas." The ingredients of this potion are presented as vignettes ranging from a frustrated woman to the problems of an adolescent. Earth Onion is a group of women from Washington, D.C. who write, direct and act their own work. Admission is 75 cents.
