This is amusing and educational:

It turns out your brain is mostly a bag of water. And water can help increase the size of an antenna and increase the transmission range. The obvious conclusion is...watch the video and find out!

Best quote comes at the end:

"I didn't believe it, and the only way of finding out whether something is true is to do the damned experiment! Find out what is reality. Disprove your prejudices!"
I'm not an EE--what am I doing here?

And it would work even better with a metal plate, or something like that.  Ground plane FTW!

Heh, that's cool. Not just improving transmission antenna gain by getting closer to a wavelength long, but also demonstrating the far more important principle of investigation by experiment.

"There is a principle, which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance - that principle is contempt prior to investigation."
-- Herbert Spencer, 1820-1903

This applies in politics and history, as well as science. Also when investigating an aircraft disappearance, in a very high disinformation-noise environment.


I'm not sure, but isn't it a sidetrack that he's talking about water? I'd have thought any conductor would do. His head (and the bottle of water) are just acting as a vertical conductor. Capacitive coupled in the case of the water bottle.

I laughed when he said "this is something everyone can try." Well, except for people who choose to drive old, non-computerized cars, like me.
First time I've ever come across a downside to that choice. Now I can't test whether it specifically has to be water. Vs any old bit of wire, or better yet a correctly tuned antenna and tank circuit.

Ah, excuses. OK, I could borrow one. And the real reason I won't do it is that I'm not curious enough about this to make the effort.

hehe, i sometimes use that technique when i forget to lock my car and walked away too far
