Salt water connection

  1. May 25, 2008 #1
    I am trying to include salt water in my Rube Goldberg project. Instead of the wires that connect a motor simply being continuous, I want to bridge a connection through salt water. Meaning, but one wire, put both ends in the solution so that the connection still works. But its not working. Are there any other ways with using water?

    btw, the simple circuit is a battery connected to a hobby motor with two wires.

    Try adding Alligator clips to both ends of the split wire, and attach a paper clip to the ends of the Alligator clips, which are opposite the wire (Assuming a 2-way alligator clip). Then, put the paper clips in the water, and make sure the wire does not touch the water.

    Also, try increasing your salt concentration.
