"Convert your car to run on tap water"! "not fake!"

[m1spw]

Someone on ebay is trying to sell a guide on how to covert your car to run on tap water only, giving you better performance and economy! How gullible can people be?

If this worked, why wouldn't everyone be doing this??? What an idiot...

I'm tempted to buy this then try and do the conversion to an old lawnmower engine or something...anyone want to chip in?
