# Pocket gravity

Hold and drag the sky to bend 1,800 orbits. Try to tear the ring apart — then let gravity gather it again.

Why does it swirl?

A sideways push keeps a falling particle circling. Here, sparks follow a softened inverse-square attraction to fixed centres. They do not attract each other. This is a playful, flat toy model in arbitrary units, not an astronomical prediction.
