Hi. There are some questions. It must be an item completely automatic or it is enough when it will stirr the liquid when you shake it? It has be a simple product in 1 part - as a traditional mug? I have an idea of a finished i-part item which stirr the liquid etc when shaked. It can be manufactured in ceramics, glass, metal, plastic - any material. There will be no visible difference un price of traditional mug and a self-stirring one.
I have a large architecture abd design experience which include problem-solving and innovative components.
Thank you.
