Any fan of the film The Hunt for Red October will remember a discussion about the ‘Caterpillar Drive’ or Magneto Hydrodynamic Drive (MHD). It’s sort of a jet engine for the water which electrifies the water (creating ions) and pushes them along using magnets.
You can build a simple MHD using nothing more than a battery, some wire, warm water, salt and pepper. Here is a video of one I built.
SAFETY: The bubbles coming off the water are hydrogen and oxygen gas. Use in a well ventilated area, away from sparks.
