This is a educational construction kit assembled from various materials (plastic, metal, etc.).
This super-fun item won the 2009 Japanese Toy Grand Prix (in the Trendy Toys category)! Using your own ingredients (whipping cream, milk and granulated sugar), you can make delicious fresh caramel treats in fun shapes! Just put the ingredients into the container and microwave for 2 minutes; turn the container's knob to stir the ingredients, and then repeat the microwaving-and-stirring cycle for a total of 10 minutes to create fresh caramel cream. Use the included spatula to transfer the cream into the trays and freeze--and in about an hour, you'll have an array of caramel candies to enjoy! With a parent's help, even little kids can have fun in the kitchen with delicious results! No batteries needed; instructions are in Japanese.
