Product Maintenance：
a.When the quicksand falls too slowly--Take Out Some Air .
There is an air adjustment hole at the top or both sides of each quicksand art. All bubbles need to be concentrated at the hole (the sand should not touch the hole behind the bubble), and then insert a syringe into the air hole to extract air.
b. When the quicksand falls too fast--Add Some Air . Make sure that all bubbles need to be concentrated at the hole (the sand should be removed completely),then use the syringe to insert a part of the air into the air hole.
1. When many small air bubbles in the quicksand layer become a particularly large air bubble, you can fill in some water at this time to supplement the evaporation of water.
Be sure to cool it with pure water or boiled water, then choose an air hole, wait for the sand to move, draw some air, and empty the regulator. Then use the regulator to pump in and add the same amount of pure water, be careful not to add too much water at one time, to prevent the glass from breaking due to excessive pressure.
