This simulates the kind of bubble formation that happens when water boils: small bubbles appear, and as they get closer to each other, they combine to form larger bubbles, which eventually pop. Written by James Macnicol; 1996.
Isto simula o tipo de formación de burbullas que acontece cando a auga ferve: van aparecendo algunhas burbulliñas que, á medida que se van aproximando, combínanse para formar burbullas maiores, as cales poderán chegar a rebentar. Escribiuno James Macnicol en 1996.
