I started investigating some ideas for a Chocolate Factory online. I found all sorts of information.
DecorationsCandy lights, candy cane fabric, chocolate soaps and lotions in bathroom, bubble machine for "Fizzy Lifting Room," giant candy made of Styrofoam balls, discs and cellophane, candy in Wonka top hat, lollipops hanging from ribbon, lick able wallpaper (melt jolly ranchers on contact paper or paper with fruit design and candy dots), red carpet, balloons with candy in them, "contract" to sign at entrance, wreath of candy, chocolate bowls (melt chocolate into foil cupcake holder), chocolate milk, glue life savers together for garland, candy house from a refrigerator box, golden eggs, make candy from poster board and construction paper (glitter glue for sugar look), friends dressed as oompa loompas, red plastic wind spinners (that looked like the candy twists in the movie), chocolate river from pudding on plastic wrap (I'm not sure how I feel about that), dangle gum drops from fishing line, large lollipops stuck in a pot with foam and colored paper shred to cover foam, glue real gumballs all over a branch and stick it in a very brightly colored pot with Easter grass.
FoodChocolate fondue. "Violet" cake of girl blown up like a balloon. Chocolate room cake with gummy bears, candy rocks, lollipops, chocolate pudding for river. Mini oompa loompa food.
InvitationGolden ticket with chocolate bar.
MusicWonka soundtrack, candy songs.
GamesMost of the games I found were for kids, but I found a couple I would enjoy.
LIFESAVER RELAY - The two teams had to race each other by passing a lifesaver from one player to the next but they could only use the crazy straws that were in their mouths.
CHOCOLATE RIVER DRINK RELAY - Two teams had to get down on their bellies with their crazy straws. Each team was given a bowl of chocolate milk with a plastic boat floating in it. Everybody had to drink from the bowl at the same time. The first team to sink their boat was the winner.
CHOCOLATE KISSES - Placed several unwrapped Hershey's Kisses on a plate, topped it with tons of Cool-Whip, sprinkles and a cherry. Each person had to find and eat their kisses without using their hands.
If/when I throw this party I would have the decorations try to recreate the chocolate room as much as possible and put a bubble machine in the bathroom . I would make as much chocolate desserts as possible and do chocolate fondue. I think the like able wallpaper would be fun as well. I would definitely have a couple friends in costume. Well, I better start saving for my purchase of massive amounts of chocolate.
