Specification: Material:Plastic Color:White Size:A4 /A5(Optional) Package List: 1 x Tray Note: First, wash the plate with water before use, then pour into the painting liquid, stir and mix with a plastic rod. Use it after a minute, if there is a bubble on the water surface, please poke it with a paint stick. Second, please shake the paint before use, which can increase the painting effect. Third, the color of the first drop will be lighter, because the pigment should react with the paint, and the previously dropped pigment can be used as the base color. Change the color to a few more drops at different angles. The pigment is dropped from the water surface by 3cm. Each time a drop of the previous pigment spreads out and then drops into the next drop. Do not drop too much, which will affect the performance. Use a small stick to draw the animation surface, make the pattern you want, and cover it with A4 paper. Remember to make sure the paper fits perfectly on the water surface, and gently lift it after 5 seconds. Tile on the ground and dry.
