The superabsorbent polymer has excellent moisture absorption and does not drain even when a small amount of pressure is applied.

The display layer 146 may be configured to maintain a state that does not show any change or reaction when bacterial contamination is normal, and to change color or exhibit a reaction when bacterial contamination is detected. For example, the display layer 146 functions as a medium in which bacteria penetrated from the contaminated sand can be cultured, and a material (in other words, a discoloration material) that induces a biological reaction with the cultured bacteria is subjected to surface treatment ( For example, it can be applied). Accordingly, if the bacteria penetrating into the display layer 146 are sufficiently cultured to react biologically, the color may be changed through reaction with a color-changing material (eg, a color-reacting material). Here, the culture medium is a nutrient material required by a culture body to culture microorganisms or animal and plant tissues as a main component, and a material for a special purpose is added and mixed. It serves to supply carbon, nitrogen, inorganic salts, and growth factors (vitamins) as nutrients, including water, which is essential for growth. On the other hand, the moisture supplied from the first base layer 145 can further enhance the function of the display layer 146 as a medium, and the light emitted from the lighting unit 130 during a sand art performance or experience is at an appropriate temperature for culturing bacteria. can provide
