Clear ant farm nest module, Size B, made from concrete and model gypsum with volcanic stone, calcium sand, and desert sand. Designed for observation and a more natural nesting environment, this module combines stable structure and moisture retention to support ant activity. Key benefits Naturalistic nest environment: Model gypsum retains moisture to support tunnel stability and more realistic substrate conditions. Concrete elements provide a durable base that resembles the ants natural habitat. Easy access and control of light: Magnetic cover plate allows quick opening and secure closing of the nest area. The insertable red shading sheet reduces visible disturbance for the colony when needed. Clear observation: Transparent construction in Color Clear lets you observe ant behavior and tunnel development without disturbing the nest. Ready materials: Includes volcanic stone, calcium sand, and desert sand to create varied textures and improve burrowing structure. Features and specifications Color: Clear Size: B Materials: Concrete, model gypsum, volcanic stone, calcium sand, desert sand Magnetic cover plate for simple removal and reattachment Insertable red shading sheet for optional lowlight conditions Stable, preformed nest structure that supports natural digging patterns How it solves common problems Reduces collapse risk through gypsum moisture retention and a solid concrete base, minimizing the need for frequent repairs to tunnels. Enables observation without frequent disturbance, thanks to the transparent exterior and optional red shading sheet for calmer colony behavior. Simplifies access for feeding, cleaning, and relocation using the magnetic cover plate. Practical use scenarios Classroom biology demonstration: Use as a visible, durable habitat to show digging, tunneling, and social behavior in a teaching setting. Home hobbyist ant keeping: Install as a primary nest module for a small colony, offering long lasting structure and controllable light exposure. Science fair or project setup: Provide a reliable observation chamber that supports experiments involving colony behavior or nest construction. Care notes Maintain appropriate moisture by misting the gypsum sparingly to preserve tunnel integrity. Use the magnetic cover and red shading sheet to manage disturbance during feeding, observation, or photography. Handle the module gently when removing the cover to avoid disrupting tunnels. This Size B clear nest module combines practical materials and userfocused features for reliable observation and nest management.
