60 is plenty if the effect is large enough. Hey, even n=4 can make for a good study. Give two of them cyanide and two of them a placebo, let all the trial-size-too-small-correlation-isnt-causation-people watch and then ask them to back up their criticism with a nice helping of the tested substance.
