How to thoroughly waterproof a Macbook? I am just now coming to know the hard limits of water destroying equipment. I don't know if it's realistic to be able to have my Macbook as a floatable rubber ducky in the bath in this day &amp; age, but products like Liquipel and commercials of scuba divers using iPads have me curious. 

Is liquipel the best protection on the market? Are there other custom shops that could do anything to make a MacBook either resistant to liquid or even waterproof?
I'm going to stick my neck and say that you cannot do this.  No matter what materials you have to hand, your MacBook requires open access to the internals via vents and grills etc for fans to push unwanted air out, or suck cooler air in etc.  You can't safely just block all this up.  You can get a wide range of keyboard covers to allow you to type with wet/dirty hands etc, but protecting the entire unit isn't really practical at all. Servers are amenable to being bathed in mineral oil but that requires special cabling, removal of all blowers and potentially modifying the heat sink depending on the specifics of the CPU and coolant temperatures.
