Increase your Car Remote's Range
I really don't know how this works.
Apparently you can extend the range of your car remote by holding the remote to your head.
In one method you simply touch the remote to your head - http://www.youtube.com/watch?v=IRQWV0Zj8Fg
In the other a more sophisticated open mouth below the chin technique is used. Unfortunately that link is censored by Q-Tel!
One scientific theory is "Most remote key fobs operate at up to and around 1 GHz. This corresponds to a wavelength of ~30cm. Whenever you have a confined cavity on the order of an integer multiple wavelengths (here 30, 60, 90cm,...), a very strong resonance can build up due to constructive interference as it bounces around. A little more or less, and a smaller resonance builds up. So theoretically, without knowing much about the skull's ability to reflect 1GHz waves or the dielectric effect of the brain and its fluids, it seems possible that the skull (~20cm average) is enhancing the signal marginally."
