stabilné peny
Explanation:
"Foams are generally unstable; they are self-destroying. Foams increase the total energy at the interfacial region, the area between the solvent and surface active agent. Foams can be stable when the surface tension of the solution is much less than the surface tension of the solvent. Persistent foams need surface active agents. Foams have a strong surface elasticity and resist external and internal stresses."

neutral  Jan Fatara: "Tazko odstranitelne p." je podla mna dost nevhodny vyraz, kedze ide o udrziavanie nemennej struktury peny, nie o jej vlastne "odstranovanie" (peny)... "Trvacne p." podla mna moze byt...
