Bro discovered density 👏 Ask yourself: how come when you throw a helium-filled balloon toward the ground in the same way, it floats upward? Does this mean balloons are "anti-gravity"? No - it means helium is less dense than air, therefore it floats upward. "Gravity" plays no part in the movement of different objects in our environment. It is 100% based on density, buoyancy, and electrostatics.
