Click / tap the stage to blow a bubble
This 2D companion replaces the original's decorative floating-bubble shader with the actual physics its title promises: each bubble's internal excess pressure is computed from the Young-Laplace law ΔP = 4γ/R, so when a small bubble touches a larger one their pressure difference drives a live volume-transfer ODE — the small one visibly shrinks and pops while the large one grows, exactly as real soap bubbles do.
