There are a lot of baby shower games out there. One of my favorites that is really easy to put together but is challenging if you're playing is "Guess the Powder."
Object of the game: Identify as many household powders as you can.
Set up: Fill 10 small, empty baby food jars with household powders such as baking soda, baking powder, corn starch, powdered sugar, cream of tartar, flour, laundry/dish detergent, powdered milk, baby powder, baby formula, etc. Number the jars 1-10. Make sure you make a key to check answers.
Pass out a pencil and paper to each player. Have them number their papers 1-10 or print out a game card here!
Playing the game: Players pass the jars around and write their guess on their paper. The number of the jar coordinates with the number on their paper.
Levels of difficulty:
You can make this game difficult by having the players only LOOK at the powder through the jar.
Make it moderate by letting the players open the jar and smell and/or touch the powder.
Make it really easy by letting the players taste the powder, though I don't recommend it.
Winner: The one with the most correct answers.
