Some snakes, like the rattlesnake and the grass snake, are venomous just when they want to.
They produce the toxic chemicals that they use to kill only when they want to eat.
Attending to this fact we decided to design a very fast and efficient system which provides the enough quantity of food that the consumer really needs and as soon as possible. So we reduce the waste generation and the consumer has not to buy food for a week, he or she gets the food that he/she wants and in the moment he/she wants.
