This weather forecast bottle uses temperature change detection to indicate weather through crystal changes inside a glass container. The solution inside the bottle comprises several chemicals and the product can be used for weather prediction as well as decoration. Key features and benefits - Visual weather indicator: temperature changes cause distinct crystal behavior that reflects current or upcoming weather. - Dual purpose: serves as a functional weather predictor and an attractive decor item for home, office, or classroom. - Simple, low maintenance: no electronics or batteries required; easy to display and enjoy. - Material and construction: glass bottle housing a multi chemical solution for stable performance. How it works - Sunny day: the filling rests at the bottom while the upper liquid remains clear. - Sunny to cloudy: the filling rises and forms visible layers. - Cloudy day: the filling floats higher and becomes more turbid. Use scenarios - Home or office desk: place on a desk or shelf to observe daily weather changes at a glance. - Classroom demonstration: use as a science aid to explain how temperature affects visual indicators and weather patterns. - Decorative display: position on a mantel, coffee table, or window sill as a unique conversation piece that also hints at the weather. This description stays aligned with the product’s glass container design, multi chemical solution, weather prediction function, and decorative capability.
