The video below by researchers at the Harvard Medical School and Technion–Israel Institute of Technology shows bacteria break zones of ever increasing concentrations of antibiotics hence demonstrates how bacteria becomes “impervious to drugs”. They are able to
In a creative stroke inspired by Hollywood wizardry, scientists from Harvard Medical School and Technion-Israel Institute of Technology have designed a simple way to observe how bacteria move as they become impervious to drugs. 
The following video seems to be the original video showing the yellow color of the bacteria.
