Operation method of quicksand painting

When operating, just hold this product for a moment or so and gently shake it to concentrate the sand in the picture on the bottom edge. At the same time, it will shake a fixed proportion of air into small bubbles and then turn them upside down horizontally. At this time, the sand flow is slow, and there is a dynamic feeling of waterfalls moving mountains. When painted, the towering mountains and the high gorge and Pinghu stand out, which is refreshing and interesting!
