When anyone refers to Science they always say them? I reckon it's some old fart sat on his backside all day going over experiments to come up with things we already had in the first place... Like touch screens... Except powdered water, this was just an amazing discovery.
What if you have no water around? Could you just add powdered water to the powdered water and get water to add to the powdered water?
Because Isaac Newton, Albert Einstein, Blaise Pascal and Nikola Tesla were not all one person. Er, no. You won't get anything, as you'll need water in the first place.
