HOW IT WORKS

Turn the sand picture over to watch the battle of the elements.
The sand just wants to settle at the bottom, the air just wants to escape to the top, the water hosts the party.
The result is the sand trickles between the air bubbles to create fascinating stratifications in the sand mountains.
You can turn the Arc Sand 180° to create breathtaking mountains, valleys, and dunes.
Or, just rotate the Arc Sand to create cascading sands.
