Buying a Blacklight?
I have seen black light bulbs that fit into a standard socket at our Walmart during the Halloween season. Perhaps your store would have some in stock - that would be much less expensive than purchasing a black light and would take up much less storage space...
Games for a Coed Wedding Shower?
How about pitting the men against the women to play trivia similar to Battle of the Sexes? You ask the men questions that women would know (like about cosmetics, fashion, etc.) and the women questions that men would know (like about cars, sports, etc.)
Buying Marble Chase?
We played this game growing up. It was put out by Milton Bradley or Hasbro under the name Aggravation. You might be able to find it online.
