Sponge Electrode Water or Saline Bottle

Sponge electrodes need to be wet to work.

Use the foc.us water bottle to wet your sponge elecrtodes.

Fill the bottle with water and then squirt some water onto the sponges when required.

You can add a very small pinch of salt to make a 0.1% saline solution. This will decrease the resistance marginally, so is not totally necessary.
