Usage Guidelines: 1. 2. The moving sand picture is a glass product. Please use with caution. Do not let children use it alone. 3. For the first use, please place the moving sand art picture on a shelf for at least 30 minutes for the first 360 degree rotation. 3. Before reversing the liquid movement of sand art, please let the sand sit for a while to form a scene. 5. Under normal circumstances, there is no need to adjust the air and water with the movement of the moving sand art fluid. There are strict initial standards for the amount of air in a moving sand painting. 6. Over time, the air inside will increase and the water may evaporate. You may need to adjust the water to air ratio. If adjustments are needed, use a small syringe to slowly inject a small amount of water or air. Do not inject too much water at once as the water pressure is too high and may break the glass. (Syringe not included) (Requires pure water) 7. There are small holes on both sides of the flowing sand art liquid motion. Find this small hole and hold the sand tray upright so the air can rise and the sand can sink. 8. Insert the syringe into the rubber and adjust water and air as necessary. The amount of water injected must be equal to the amount of air pumped out. Also, don't do it too many times as it may damage the airtightness of the rubber. The sand is falling too fast. Inject a small amount of air. The sand is falling too slowly.
