Some basic physical properties of soap bubble were studied from the optical ,mechanical and thermal point of view to broaden the teaching ideas of university physics experiments .The refrac-tive index and thickness of the soap bubble w ere accurately measured using optical interference princi-ple and then its mass w as determined using the force balance principle .T he surface tension coefficient of the soap bubble was achieved using pull-off method;the surface free energy and the pressure differ-ence inside and outside the soap bubble were calculated .
