Elasticity of diameter testing is tested with three band of condom. The most diameter is Durex, Next Playboy and the last is One Touch. One Touch is tearer than Playboy. Playboy tearer than Durex.
Each brand of condom has different components. Different components are cause of different elasticity. This is random experiment so it has some error datos. Such as error from measure, cone has rough surface, pull-action when we tested. These factors are cause of error experiment. We hope our experiment is useful for leaning.
