"I took a 12 Volt battery and connected its positive terminal to one end of an LED bulb with enough series protection resistor. Then I connected the other end of the LED bulb to earth (soil with moisture outside my house). I did not connect the negative terminal of the battery to anything. I expected the bulb to glow, but it did not glow until I connected the negative terminal of the battery to the ground as well." This is apparently how Imtotob completes his circuit as stated by him in :18 seconds of his video. He registors zero amp draw! It's important to note that you can't use the same point for the battery Earth Ground! You need two different Earth Grounds! This completes the circuit. The voltage differential between the grounds generates the transverse oscillation in the standing wave!
Here's a great video by Bill Nye on the electrical circuit:

Thank you for the link to this great vid. I will show it to my daughter  :)
