water two simple hydrogen atoms merged with a single oxygen one to create the harbinger of all life in the universe it is Earth's most precious resource but it's also the substance most responsible for ruining our favorite outfits electronics and parades since the very beginning of time and that is why waterproofing techniques have been on the forefront of technological advances since well technology was invented and although nature provided us with rudimentary water protection in the form of tree branches and caves it quickly became apparent that we needed to protect our warm-blooded selves and tribe mates from the harsh thermal robbing effects of constant drenching these evolving forms of water protection came to be measured by their ability to resist humid and damp conditions known as damp proofing or their ability to resist water infiltration known as waterproofing now water and dampness resisting techniques usually involve covering an object with something that will help it to repel liquids the original Scotchgard treatment from 3m is a great example it was used on furniture and clothing inherently porous materials to resist water penetration and prevent stains from spills but modern science has taught us that just because we can doesn't mean that we should and the fluorocarbons used in the original formulation of this product we're capable of causing liver failure and birth defects so new techniques needed to be developed both to overcome those downsides and in response to new demands like that pee repelling wall paint that causes public urinators to accidentally soak their pants and shoes or bringing it back somewhat more on topic the developments in the protection of electronics where they originally turned to cumbersome physical barriers that either prevented or impeded their use but had thanks to modern technologies like the 2013 development of nano material coating 1000th as thick as a human hair are now able to protect electronics by just covering them with this tiny layer that forces liquid molecules to bead and roll off of surfaces without penetrating them allowing for things like the new waterproof mobile devices that we've seen with some relying on rubber barriers for extra protection but others leaving exposed their headphone and power jack so going bareback but these methods also aren't the be-all and end-all of waterproofing techniques and whatever a manufacturer may claim the best way to prevent water damage is still to keep your stuff from getting in contact with water which is why waterproof headphone jacks often still have a little rubber seal at their base and serious waterproof items like pelican hardcases usually follow the old steadfast method of encasing an item in something durable and then tightly sealing it in which carries the added benefit of decreasing an object's vulnerability to higher water or atmospheric pressure often measured in numbers atmosphere with each digit representing 10 meters of depth with the only disadvantage to this technique being that it also restricts access to a containers contents and anyway unless total submersion is the plan more often than not water resisting techniques combined with our final waterproofing strategy controlling and routing fluids around is amply effective you'll see this method used in the overflow port on your bathtub on your house in the form of a waterproof roof and gutters to keep liquid from pooling and penetrating and even in Lenovo's water rerouting ThinkPad keyboard which can survive a direct spill on top of it but that's the key to all of this I guess a spill just because an item is rated for a general type of water protection and you can learn more about these standardized ratings up here that does not mean that it will stand up to prolonged or extreme exposure cases like rugged water sports for adventures in the salty blue sea there is a big difference between long-term solutions and protective measures so just because that new phone is rated at safe 200 meters or whatever that is not an invitation to make dropping it in the toilet a morning routine especially for coffee drinkers speaking of morning routines it sure is hard to get up in the morning if you stayed all linked reconciling your accounting numbers and you know logging your hours for jobs no no no forget about that freshbooks is the
