Abstract This study addresses the pedagogical challenges associated with teaching the abstract concept of intermolecular forces in high school chemistry by employing bubble formation as an engaging experimental model. Through systematic investigation of bubble solution formulations,key performance parameters including maximum bubble volume,lifespan,surface tension,viscosity,and evaporation rate were evaluated. The optimized composition of 10% detergent and 0.6% guar gum was demonstrated to surpass commercial bubble solutions in overall performance. Mechanistic analysis revealed that detergent components reduced surface tension and imparted self-healing properties while retarding liquid evaporation,whereas guar gum enhanced viscosity and inhibited drainage. The synergistic combination of these components significantly improves the stability of bubbles. This simple yet intriguing experiment effectively visualizes abstract chemical principles,providing a valuable platform for extracurricular scientific exploration.
