You can manually press the ball to roll into a gravitational field similar to the gravity well. It is super interesting to watch the process of the ball rotating around the center, like this Infinite loop, hence the name infinite black hole. [Gravity well description] A gravity well is a conceptual model of the gravitational field surrounding a celestial body in space. The greater the mass of the celestial body, the deeper the gravity well and the wider its range. Just like placing an iron ball on a piece of supported cloth, the cloth around the iron ball will dent downwards. Similarly, large celestial bodies can also create similar dents in the surrounding space, and the surrounding small celestial bodies will sink into the depression. , gravity may be generated in this way. 【product features】 1️⃣ The simulated gravity well phenomenon has become a reality and is no longer beyond imagination. 2️⃣ The process of rolling steel balls in the gravitational field of the gravity well is super healing and interesting 3️⃣ The golden ratio of pressing and elastic structure makes you addictive in the hand. 4️⃣ Detailed assembly instruction videos can greatly increase the chance of successful assembly. 5️⃣ Comes with 11 small steel balls 6️⃣ Safe polyester is used for assembly and bonding.
