2. Pick up the sand painting and shake it gently to turn the air inside into small bubbles, then turn it over to let the sand slowly flow down from the small bubbles.

3. After the sand has completely fallen, let it sit on the shelf for no less than 30 minutes, and then turn it over.

Kindly Reminders:

1. Please don’t use excessive force when shaking the sand painting. If you use too much force and the bubbles are small and dense, the buoyancy of the bubbles will be too great, the sand may fall too slowly, which makes it looks like that sand cannot flow down.

2. If you accidentally let the air become small and dense bubbles, you only need to let it stand for a few hours or days, and the bubbles will gradually become larger and disappear.

3. After each flow, let it stay on the shelf for no less than 30 minutes to allow the sand to compact. If you turn it over immediately after each flow, because the sand is too loose, it’ll fall in large pieces soon, so you’ll be able to’t see the scenery of the sand slowly falling.

4. The ratio of air and water has been balanced before leaving the factory. Under normal circumstances, there is not any need to adjust air and water.

5. If you wish to adjust the water and air, be careful not to add too much water at once. If the water pressure is too high, the glass will shatter.

Special Notice:

There are strict initial standards for the amount of air in sand paintings. Water will evaporate, because there is not any absolutely airtight environment for this handmade product. Over time, the air inside may increase. In the hot summer, water will evaporate faster. At this time, the amount of air may need to be adjusted. This is easy to handle. You want a syringe with a thin needle and some clean water. A disposable syringe is sufficient. There is a small hole on the side of the rubber ring. Find the small hole and let the air come up and the sand sink. Insert the syringe into the rubber to adjust the water and air. The number of bubbles will directly have an effect on the speed of the quicksand. The more air, the slower the flow rate. And the less air, the faster the flow rate. The most important thing is that the amount of water injected is the same as the amount of air extracted. In addition, please do not do this too many times, as this may damage the air tightness of the rubber.

Unfortunately, syringes and needles are medical equipment and dangerous goods, and we cannot provide you with them. If needed, you’ll be able to buy it at a pharmacy or other store. A small disposable syringe is enough.
