Is it really that the robot can one bacteria at a time to the sink or can it take one group of the same color at a time to the sink? It seems it will take forever to take all the bacteria to the sink if we attempt to do that. Whatever I read seems to indicate that it is one bacteria at a time but I just want to get clarification if it is single one or the group of one color. Appreciate your response.
