    Abstract: An adhesive composition includes an organic adhesive material and a sand. The organic adhesive material includes a water-soluble adhesive and a starch, wherein a weight of the organic adhesive material accounts for 4 wt % to 70 wt % of an overall weight of the adhesive composition, and a weight of the sand accounts for 30 wt % to 96 wt % of the overall weight of the adhesive composition. A water-soluble adhesive mixture includes the adhesive composition and an aqueous solution, which are mixed to form a viscous mixture (i.e., the water-soluble adhesive mixture). The water-soluble adhesive mixture has an adhering function for users to apply to and adhere to a surface of toys, so that the toys could be adhered together to form a toy model. As the water-soluble adhesive could be softened and dissolved when the water-soluble adhesive mixture is immersed in water, the toy model could be disassembled easily.
