Tides are the periodic rise and fall of ocean water on Earth caused by the gravitational pull of the Moon and the Sun. The core cause lies in "tidal force"—the difference in the gravitational pull of celestial bodies (mainly the Moon and the Sun) on different points on Earth. Although small, the Moon is closest to Earth, and its tidal force is more than twice that of the Sun, making it the dominant force. When the Moon, Earth, and Sun are aligned (new moon, full moon), the tidal forces of the Moon and the Sun combine, forming a "spring tide"; when they are at right angles (first quarter, last quarter), the tidal forces partially cancel each other out, forming a "neap tide." This is not only a magnificent natural phenomenon but also contains enormous tidal energy, a renewable and clean energy source. Our interactive exhibit on "Tides" uses a sophisticated three-sphere model of the Sun, Earth, and Moon to make this complex celestial mechanics process clear and operable. At the center of
The ancient mythological image of the "Magpie Bridge" has now become the name of a landmark project in China's deep space exploration. "Magpie Bridge" is the world's first relay communication satellite operating at the Earth-Moon Lagrange point L2. Because the Moon always presents only one side to Earth (tidal locking), when a probe lands on the far side of the Moon, it loses direct radio contact with Earth. To solve this communication problem, "Magpie Bridge" was precisely deployed at the L2 point, a special gravitational equilibrium position, allowing it to "overlook" the far side of the Moon and Earth, acting as a perpetual "space signal tower." It relayed commands from Earth to the probe on the far side of the Moon and transmitted the scientific data collected by the probe back to Earth in real time, achieving a historic breakthrough in human exploration of the far side of the Moon. Our "Magpie Bridge Connects Hearts" interactive exhibit, on a square platform with sides of 1.83 me

In this age of information overload, effective health communication is no longer a one-way transmission of information, but rather requires stimulating public initiative and choice. Designing the learning process as a gamified "choice-exploration" cycle can significantly enhance participant engagement and retention. The interactive spinning wheel, a classic tool for random selection and direction, has been given a new educational mission in this context: it encapsulates knowledge about various infectious diseases behind equal options, allowing visitors to randomly or autonomously "unlock" a learning topic by "spinning"—a ritualistic and slightly uncertain action. This model not only increases the fun and anticipation of learning, but more importantly, it metaphorically represents the inherent uncertainty of infectious disease risks—we cannot predict what pathogen we might encounter next, thus requiring broad knowledge and preparation. The "Common Infectious Diseases" exhibit cleverly

In the vast solar system, contrast is the key to understanding. By juxtaposing Jupiter and Neptune, we can clearly see that despite both being gas giants with massive and persistent storms, their appearances are vastly different. Jupiter's Great Red Spot is a striking reddish-brown, likely caused by complex photochemical reactions in its upper atmosphere exposed to solar ultraviolet radiation; while Neptune's Great Dark Spot is a deep blue, believed to be caused by a hole in its upper atmosphere's methane ice clouds, exposing darker, warmer clouds below. This difference in color and shape directly reflects the differences in the two planets' distance from the Sun (resulting in different amounts of solar radiation), their atmospheric composition and vertical structure, and their internal energy-driving mechanisms. Observing them is like reading two different textbooks on planetary evolution and atmospheric physics. Standing in front of the "Jupiter & Neptune Storms" exhibit, you feel a
Stress is a multi-dimensional concept; it is both a measurable physical quantity and a perceptible psychological state. A cleverly designed interactive installation can externalize this duality: by materializing abstract stress (such as tasks or expectations) into concrete, countable entities (small balls), and metaphorically representing systems under stress (such as individuals or teams) as a physical structure (a dome) with a critical load-bearing capacity. Participants can intuitively experience the entire process from calm accumulation to tense equilibrium, and finally to a critical collapse or release, by adding "stress sources" themselves. This hands-on participation is more effective than any preaching in understanding the importance of "prevention is better than cure" and "timely relief." The "Facing Stress" exhibit (1400*1400*2200mm) invites you to become the "director" of this mechanical drama. Standing in front of the installation, you personally decide how many "stress ba
In the normal temperature world, objects are grounded by gravity. Superconducting technology, however, presents a fascinating drama of "anti-gravity." Its core secret lies in the Meissner effect: materials in a superconducting state completely expel their internal magnetic field, generating a powerful repulsive force against external magnetic fields. Imagine a powerful magnet trying to approach a superconductor; it seems to encounter an invisible, indestructible "magnetic wall," and is steadily held aloft. Placing such a superconductor at the bottom of a train, with an array of permanent magnets laid on the track, allows the train to achieve self-stable levitation through this continuous repulsive force. This is not magic, but a song of ice and fire played by quantum mechanics in the macroscopic world—a technological epic composed by extreme low temperatures (superconductivity) and controllable magnetic fields (levitation). Our "Superconducting Levitation Train" exhibit is like a mini
Understanding tides requires constructing a dynamic, three-dimensional spatial mental model. Simply knowing that the moon's gravity is the primary cause is insufficient; the key lies in understanding how the direction of the moon's gravitational pull on any point on Earth changes periodically with the Earth's rotation and the moon's revolution, and when the sun's gravity "enhances" or "weakens" this effect. Designing this process as an interactive model that can be manually adjusted and provides real-time voice feedback transforms learners from passive recipients of information into active "explorers" constructing knowledge. By manually arranging celestial bodies and immediately hearing and seeing the corresponding scientific explanations and phenomenon simulations, the complex causal chain is broken down into a series of verifiable and understandable steps. At the "Tides" exhibit, you hold not just a spinning wheel, but a key to exploring the laws of the universe. On the display stan
Human exploration of the moon has never ceased. The far side of the moon, however, remained a "secret realm" long beyond human sight. The launch of China's "Queqiao" relay satellite is like illuminating an ever-burning "lighthouse" for this secret realm. It hovers quietly at a special equilibrium point (L2 point) in the Earth-Moon gravitational system, faithfully playing the dual role of "messenger" and "guardian." This is not only a victory for engineering but also a poetic cosmic vision: using human wisdom to build a stable information bridge between two celestial bodies in the boundless cosmos, making "communication" transcend myth and become reality. The communication beam emitted from "Queqiao" towards the far side of the moon is like a "gaze" of care and curiosity cast upon the unknown universe. Our "Queqiao Communication" exhibit (1830*1830*1200mm) cleverly blends this cosmic romance with rigorous engineering. Once activated, the elegant movement of the Earth-Moon model establi
