      Hey Fin and human girl,

      I actually want to make flexible chocolate (they will taste like chocolate buttons) in order to use it as a means to show students like yourself how we can manipulate materials and make them do unexpected things.

      By using pressure rather than heat, I can make the structure of the cocoa fat in the chocolate become more fluid without melting the chocolate solids. That way, the resulting thin string of chocolate (the pressure is generated by forcing the chocolate through a very small hole) will be flexible, rather like a shoe lace.

      It’s not really to sell a product but really to explain how many interesting things we can do with engineering when we understand materials and how they work and how we can control their properties.
