It seems that the effective range of the remote control will increase when passing through the skull

The remote control type key that can open the car door even from a distance is convenient, but only when you are in a hurry due to a sudden heavy rain, there is nothing wrong with the signal being unreachable.

It seems that a valid method at that time uses "your own skull (bone) bone", but when you actually tried it, it seems that surprising results have come out.

Shock movies are from the following.

I am amazed that the distance is really growing. With this condition you can not expand the effective range of television remote control, Wii remote control, mobile phone, One Seg broadcast, wireless LAN radio waves ... etc.

Anyway, what exactly is this the principle? Or something trick?
