1. A method of manufacturing a toy using a model frame in liquid comprising the steps of:
filling a water tank with a certain amount of water so that a model frame can be completely immersed;
dissolving calcium chloride, a powder component, into the water filled in the water tank;
wherein the amount of calcium chloride is determined in anticipation of the degree of gelation by chemical action with sodium alginate,
filling a liquid paint into the model frame;
wherein the liquid paint is comprised water 96 wt. %, CNC 0.99 wt. %, sodium alginate 3 wt. %, luminous material 0.01 wt. % or water 91 wt. %, CNC 1 wt. %, sodium alginate 3 wt. %, shiny material 5 wt. % or water 96 wt. %, CNC 0.99 wt. %, sodium alginate 3 wt. %, color conversion material 0.01 wt. %,
wherein the liquid paint is added with a predetermined dye and has a predetermined viscosity;
immersing the model frame filled with the liquid paint in the water tank;
solidifying and shrinking the liquid paint filled in the model frame immersed in the water tank; and
shaking the model frame so that the solidified and contracted toy is separated from the model frame;
wherein the toy separated from the model frame maintains its shape in the liquid of the water tank, and is deformed when taken out of the water tank.
