This design transforms the shape of the volcano into an intention, and uses the shape elements of the volcano and the humidifier to closely combine. Translucent frosted acrylic is used as the volcanic base to facilitate observation of the boiling state of bubbles inside the volcano. Then frosted plastic is used as the upper cover and soft silica gel is used as the upper cover to simulate the effect of snow on the volcano. This product is a simple and interesting design.
