First of all, the game of sand and water is undoubtedly one of children's favorite games. Every summer, the beach and swimming pool are simply playgrounds for children. The reason is that, first of all, water and sand are very plastic, and children can change their shapes at will. For example, building castles with sand, digging caves and so on, such activities improve children's creativity and imagination. Secondly, from the growth characteristics of children, children mainly know the world through games and play. Playing with water and sand is a good opportunity for children to get close to nature and understand it. Sand and water can improve their perception of natural things, exercise their brain thinking and satisfy their desire to explore. So, don't kill the fun of children playing with water and sand. Human nature likes something more comfortable.

Second, play with sand. Children play in the sandpit, and it is very comfortable to step on the soft sand, and then the soles of their feet are the places where nerve cells are sensitive and concentrated. This slight stimulation will make them feel happy, and then many things can be buried in the sand for treasure hunting, such as finding small shells or finding special things, which is also the source of children's happiness. Play with water. As for playing with water, it should be in summer or when the weather is warmer. At this time, water gives people a much more comfortable feeling. For example, when swimming, the feeling of being in the water can float, and the body is all wrapped in the water. It feels great. So I said I like to play with sand and water.

Third, the desire to create, the age of the child is the most creative age. When sand and water are combined, you can get the general appearance of the building you want in your hand. If you have skills, it is not impossible to make it more exquisite. The sense of accomplishment after finishing a work is unparalleled. It can not only satisfy your own creative desire, but also have a sense of accomplishment. This is something that even adults like. So I can understand why so many people like my world.
