Sucking on an iPhone 5 charger?

Ok so, my 18 month old niece is going through this stage of wanting to put all chargers in her mouth and when I baby sit her she feels compelled to suck on my phone charger, now it hasn't been plugged in when she gas but if she got a hold of it when it was plugged in and put it in her mouth there would have to be a safety mechanism to stop electrocution wouldn't it?

How about keeping the chargers away from her?

Umm no

Umm no… Your fingers don't get zapped die to the outer guard on the micro USB stick… But electricity is still inside the wiring… And liquid can get into the nooks of the cord/guard…

liquid + Electricty = ZAP!

give it a whirl… Physics and electro-magnistism is awesome, isn't it!
