Some fun ideas for a Willy Wonka birthday party include buying or making Wonka Bars with golden tickets inside that act as the party invitations and creating a food and drink table that replicates the chocolate garden. Other ideas are to label glass bottle of lemonade or sparkling drinks as "Fizzy Lifting Drink" and to create a treasure hunt using clues written on the backs of golden tickets or candies that lead to prizes for everyone.
On the food and drinks table, topiaries make good foundations for skewers of cheese, tomatoes, fruit or marshmallows. At the center of the table, a chocolate fountain or fondue ties the theme together. The table can be covered in green coconut grass, and the host can arrange various snacks and colorful containers of candies around the fountain.
In the treasure hunt, the tickets should all have numbers written in glitter glue. The number each kid is given corresponds to a hidden prize at the party. Prizes can include children's books and copies of the Wonka movies.
Another fun idea is to create a separate "Invention Room" at the party. This is a craft room where kids at the party create and decorate cupcakes, cookies or various crafts, such as clay figures.
