I've been plunging through the world of Avatar: The Last Airbender, and I started thinking about how cool it would be if it could be possible in real life. Then, I thought about how it would work. You just need to attract and repel water, correct (hint hint, magnets), right? But, how would you magnetize water? That's where electromagnetism comes in. By sending electricity through water (not pure water), it would conduct the electricity throughout the body of water, therefore generating a magnetic field. Then, lightweight gauntlets with very powerful magnets inside could attract or repel the water. Could anyone point out anything wrong with my theory so I could tweak it to perfection? I really want to get this idea out.
