So, you want to carry water onboard, but it’s just too heavy ? Read this.....

so you want to bring a case or two of water on board, but the weight is prohibitive.   I have found the solution.  First, you’ll need a food dehydrator. Second, you’ll need ice cube trays.

okay, here we go.


1) fill the ice cube trays with water

2) turn your dehydrator up to the highest setting

3) place the ice cube trays onto the dehydrator trays, and stack them as high as you  can.  Let sit overnight, or until the water is dehydrated.  To test for doneness, dip a toothpick into the ice cube tray.  If it comes back wet, your  water is not fully dehydrated.  

4) leave dehydrated water in the trays when done.  Let cool, and place trays into ziplock bags.

5) when you want water, fill a tray with water to rehydrate the dehydrated product.  Wait 5 minutes,  and enjoy !

Why not just make your own water once on the ship, nothing to carry just air. Air is free and all around. Take 2 parts Hydrogen and 1 part Oxygen . And you have water? Seems like less work than your way..... Or the water on the ships which I believe i better than most public water in America.

And Yes I understand the posting of this thread,

It’s not as easy as you’d think. To pull a bunch of Hydrogen atoms, and mix them with a bunch of Oxygen atoms. It’s not like tossing a salad. You need heat. You also need to filter out Nitrogen, CO, CO2, plus a plethora of contaminants.

My way, once the water is dehydrated, you can dump the cubes in a ziplock bag, and pack them away. Once in your cabin, or as needed, pull out a bag, fill it with tap water, and wait for the water to rehydrate. 3-5 minutes usually.

Another problem with making water from scratch is, if not done perfectly, you may end up with a batch of dihydrogen monoxide.

Kergan - instead of taking the trays in your suitcase, why not dump the dehydrated cubes into a large empty water bottle?

‘You could. But ziplock bags get somewhat flat. You can carry a couple of gallons of dehydrated water and take up very little space in your luggage.

that dihydrogen monoxide is dangerous. Especially if it gets into your lungs.

Making Dihydrogen Monoxide is kinda my point..... Does the World really need the gene pool with people in it who can spend thousands on a cruise and are to cheap to send $20 more on water, or not smart enough to use the water provide on the ship.

It is just natural. I call your attention to Darwin's Theory of Evolution by Natural Selection. More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

I call it, culling the herd.

I’ve seen people with hand carts with water and soda getting on board. Ridicululous.

Those are the same people boarding with their emotional support animals, dressed in costumes right?

While I would agree that a person cancelling their existence by creating an abundance of dihydrogen monoxide in a small, closed environment is not necessarily a bad thing, what about the other 3000 passengers on the same cruise ship? Should they be forced to cease their existance because of the carelessness of one individual?

And you have fallen for a a internet hoax.

What does dihydrogen monoxide mean?
Dihydrogen monoxide is a technically correct, though rarely used chemical name for water. It has been employed as a hoax to evoke fear in the minds of people who are scientifically uninformed. This term is never used by actual scientists, that is, unless they are behind a pranking attempt.
