|Remember, there is acid in those batteries !|
Denob over at The Prepared Canadian was the first to put up this video. Please check out his site, certainly if you are Canadian, and even if you're not.
I am also pleased to bring it to the attention of readers here. John Milandred, in the video, is my old boss. He was the original producer to Rational Preparedness when it was a radio show on Monday evenings between 8 pm and 9. To say that this man is mechanical would be like saying that the Atlantic Ocean is a little bit wet. John is a very bright guy. Of course, if you decide to do this, make sure you implement all the safety precautions John mentions.
