There are several concepts we, as parents, seek to explain to the curious minds of children. Sometimes, the absence of some thing/phenomenon explains the importance of that thing/phenomenon in a powerful way. For instance, What if there is no water? It allows the child to flex the thinking muscles and also appreciate the importance of water.
This can be played as a game with your little ones. We can increase the complexity based on the age group.
