The "Hun Tian" theory posited that the celestial bodies were like the yolk of an egg, with the heavens being the shell, and the Earth suspended in water, surrounded by the sky. "Can the orrery truly observe the stars?" This was a question posed even in Zhang Heng's time. To prove its capability, he conducted an indoor test. Based on the star positions indicated by the orrery, he accurately predicted the locations of stars, which matched observations made outdoors. This convinced everyone that the orrery could accurately measure celestial phenomena! **Orrery Introduction** https://www.youtube.com/watch?v=-yDAQfmaENs **➤ Product Details** Difficulty Level: ★★★★☆ Assembly Time: Approx. 2.5-3 hours Recommended Age: 14+ Product Dimensions: 12cm x 12cm x 18cm Package Dimensions: 27cm x 16.5cm x 4.3cm Materials: Eco-friendly non-toxic wood, PMMA Origin: Taiwan **➤ Precautions** • Please use the included sandpaper to smooth wooden parts before assembly.
