Press a velvet block onto a master plate without Cipro, and then plate the replica plate on medium with Cipro.

Press a velvet block onto a master plate without Cipro, and then plate the replica plate on medium with no Cipro.

Press a velvet block onto a master plate with cells that are able to grow in medium with Cipro, and then plate this on a replica plate that contains medium with no Cipro.

You would not be able to use this method because all of the bacteria would die on the original culture plate.
