What a great invention idea Annabelle. You might know this but our chief inventor Dominic is very particular about the temperature of his drinks, so this invention would be very useful for him! We especially like that you have used solar energy to make your milk colder work, at Little Inventors we like any invention that is good for the environment, so this is great. We think the voice activation is a handy idea too. Keep inventing, Little Inventor!
