Appaday 142 Grain Garden

A falling sand garden. Pour sand, water, acid, lava, stone, wood, plant, and fire, and watch them fall, flow, and react. Water quenches lava into stone, fire races through wood, acid eats what it touches, and plants drink up water. Flip gravity or tilt your phone, then save a crisp PNG.
