My conductance sensor doesn't work but if i connect an alligator clip and dip that in liquid it works. Any ideas why?

Hi KyleG04,

Did you buy the Science Buddies kit or did you supply your own materials? If you bought your own materials separately, are you sure you bought bare copper wire and not insulated wire?
