- Place the sand painting on a shelf for at least 30 minutes.
- When you operate it, just hold and shake it gently left and right for a while, so that the air bubbles inside become small bubbles, then turn it over to let the sand slowly flow down from the small bubbles.Note: It is normal for some bubbles to get stuck.Because the buoyancy of the bubbles is balanced with the gravity of the sand,but the situation rarely happens.
- After the sand has completely fallen, keep it on the shelf for at least 30 minutes, then turn it over.
Quicksand falls too slowly: pump out some air bubbles
Quicksand falls too fast: add some air bubbles
Turn the sand painting to make the bubbles move near the air hole and make sure there is no sand near the air hole. Insert a syringe into the air hole to adjust the bubbles.
Unfortunately, we can’t provide syringes and needles. Maybe you can buy it at a pharmacy or other store if needed. A small disposable syringe is enough.
