● NOTE: The air is about 5mm high, the sand will reach a good flow rate.
Quicksand falling too fast: add some air
1, the same method as above, focus the air to any one of the corners with air holes, to determine the sand move away.
2、Insert the air hole with an air regulator.
Quicksand falling too slow: pump out some air
1、Each round quicksand art painting has a hole, concentrate the air to any corner with air hole , Wait for the sand to move away.
2、Insert an air regulator into the air hole.
If a lot of small bubbles in the quicksand painting become a particularly large bubble, this time can be filled with a little water to replenish the evaporation of water.
1、Be sure to use pure water or boiled water to cool;
2、Select an air hole, wait for the sand to move away, pump out some air and empty the air regulator tube;
3、Then use the air regulator to pump in and fill with too much water to prevent the pressure from being too high and the glass from breaking.
