3D underwater landscape hourglass

2☘ If the sand falls too quickly, there may not be enough air bubbles in the hourglass. Use a syringe to add some air bubbles through the air inlet hole until the sand flows at the desired speed.

3☘ To adjust the bubbles, rotate the hourglass so that the bubbles move near the air inlet hole and make sure no sand is near the air inlet hole. Then insert a syringe into the air inlet hole and adjust the amount of air bubbles as needed.

4☘ Note: It’s important to handle the hourglass with care to avoid damaging the delicate glass and the sand inside.

Specifications: Material: Glass, moving sand

What do I do if the sand doesn’t fall or falls too quickly?

1. What should I do if the sand doesn’t fall or falls too quickly?
2. A: To create finer bubbles, gently shake the sand picture. The smaller the bubbles, the more dramatic the resulting landscapes will be.A: If it hasn’t been used for a few weeks, you may need to tap the sand picture lightly to get the sand moving again.

   Do I ever need to add water? What kind of water should I use?

3. A: Yes, possibly once a year. Over time, water may evaporate. We recommend using “spring water” as the best option to replace evaporated water.A: Please DO NOT remove the water from your sand picture. You don’t need to add much water, maybe just a few milliliters. Do not overfill. The glass could crack due to pressure.

   Will it leak?

4. A: With proper use of the injector and normal handling, water shouldn’t leak. However, there might be minimal evaporation through the sealant.Will I get the same sand creation every time I flip it?
5. A: No, each flip will be fascinatingly different. In fact, it will be hypnotizing.
