WEBVTT 00:00:00.199 --> 00:00:07.560 water two simple hydrogen atoms merged with a single oxygen one to create the 00:00:05.080 --> 00:00:12.840 harbinger of all life in the universe it is Earth's most precious resource but 00:00:10.480 --> 00:00:17.199 it's also the substance most responsible for ruining our favorite outfits 00:00:14.879 --> 00:00:21.119 electronics and parades since the very beginning of time and that is why 00:00:19.320 --> 00:00:26.880 waterproofing techniques have been on the Forefront of technological advances 00:00:23.599 --> 00:00:28.599 since well technology was invented and 00:00:26.880 --> 00:00:33.320 although nature provided us with rudimentary water protection in the form 00:00:30.480 --> 00:00:37.440 of tree branches and caves it quickly became apparent that we needed to 00:00:34.920 --> 00:00:42.879 protect our warm-blooded selves and tribemates from the harsh thermal 00:00:39.840 --> 00:00:44.960 robbing effects of constant drenching 00:00:42.879 --> 00:00:50.000 these evolving forms of water protection came to be measured by their ability to 00:00:47.360 --> 00:00:55.640 resist humid and damp conditions known as damp proofing or their ability to 00:00:52.640 --> 00:00:57.920 resist water infiltration known as 00:00:55.640 --> 00:01:02.160 waterproofing now water and dampness resisting techniques usually involve 00:01:00.280 --> 00:01:06.840 covering an object with something that will help it to repel liquids the 00:01:04.519 --> 00:01:11.400 original Scotch Guard treatment from 3M is a great example it was used on 00:01:08.920 --> 00:01:15.680 furniture and clothing inherently porous materials to resist water penetration 00:01:13.479 --> 00:01:19.720 and prevent stains from spills but modern science has taught us that just 00:01:17.479 --> 00:01:24.200 because we can doesn't mean that we should and the fluorocarbons used in the 00:01:22.119 --> 00:01:28.560 original formulation of this product were capable of causing liver failure 00:01:26.079 --> 00:01:33.360 and birth defects so new techniques needed to be developed both to overcome 00:01:30.560 --> 00:01:38.280 those downsides and in response to new demands like that uh PE repelling wall 00:01:35.960 --> 00:01:42.399 paint that causes public urinators to accidentally soak their pants and shoes 00:01:40.119 --> 00:01:46.520 or bringing it back somewhat more on topic the developments in the protection 00:01:44.200 --> 00:01:51.119 of electronics where they originally turned to cumbersome physical barriers 00:01:49.000 --> 00:01:55.479 that either prevented or impeded their use but have thanks to Modern 00:01:53.079 --> 00:02:01.680 Technologies like the 2013 development of nanomaterial coating 1,000th as thick 00:01:59.360 --> 00:02:06.159 as a human and hair are now able to protect Electronics by just covering 00:02:03.640 --> 00:02:11.560 them with this tiny layer that forces liquid molecules to bead and roll off of 00:02:09.160 --> 00:02:15.239 surfaces without penetrating them allowing for things like the new 00:02:13.360 --> 00:02:19.920 waterproof mobile devices that we've seen with some relying on rubber 00:02:17.239 --> 00:02:24.640 barriers for Extra Protection but others leaving exposed their headphone and 00:02:22.080 --> 00:02:29.000 power Jacks they're going be back but these methods also aren't the Beall and 00:02:26.879 --> 00:02:33.879 end all of waterproofing techniques and whatever a manufact urer may claim the 00:02:31.879 --> 00:02:38.680 best way to prevent water damage is still to keep your stuff from getting in 00:02:36.519 --> 00:02:43.200 contact with water which is why waterproof headphone Jacks often still 00:02:41.440 --> 00:02:48.440 have a little Rubber seal at their base and serious waterproof items like 00:02:45.680 --> 00:02:53.200 Pelican hard cases usually follow the old steadfast method of encasing an item 00:02:51.280 --> 00:02:57.239 in something durable and then tightly sealing it in which carries the added 00:02:55.000 --> 00:03:02.239 benefit of decreasing an object's vulnerability to higher water or 00:02:59.840 --> 00:03:07.840 atmospheric pressure often measured in numbers atmosphere with each digit 00:03:04.560 --> 00:03:09.840 representing 10 m of depth with the only 00:03:07.840 --> 00:03:15.200 disadvantage to this technique being that it also restricts access to a 00:03:12.319 --> 00:03:20.080 container's contents and anyway unless total submersion is the plan more often 00:03:17.560 --> 00:03:25.200 than not water resisting techniques combined with our final waterproofing 00:03:22.120 --> 00:03:28.239 strategy controlling and routing fluids 00:03:25.200 --> 00:03:30.560 around is amply effective you'll see 00:03:28.239 --> 00:03:35.720 this method used in the over flow port on your bathtub on your house in the 00:03:33.040 --> 00:03:40.239 form of a waterproof roof and gutters to keep liquid from pooling and penetrating 00:03:38.040 --> 00:03:46.080 and even in lenovo's water rerouting ThinkPad keyboard which can survive a 00:03:42.799 --> 00:03:49.840 direct spill on top of it but that's the 00:03:46.080 --> 00:03:52.040 key to all of this I guess a spill just 00:03:49.840 --> 00:03:55.439 because an item is rated for a general type of water protection and you can 00:03:53.519 --> 00:04:00.519 learn more about these standardized ratings up here that does not mean that 00:03:57.879 --> 00:04:06.360 it will stand up to prolonged or extreme exposure cases like rugged water sports 00:04:03.519 --> 00:04:10.400 or adventures in the salty blue sea there's a big difference between 00:04:07.920 --> 00:04:14.720 long-term Solutions and protective measures so just because that new phone 00:04:12.319 --> 00:04:18.759 is rated at safe to however many meters or whatever that is not an invitation to 00:04:16.880 --> 00:04:23.080 make dropping it in the toilet a morning routine especially for coffee drinkers 00:04:21.400 --> 00:04:27.440 speaking of morning routines it sure is hard to get up in 00:04:25.360 --> 00:04:32.720 the morning if you stayed up all late reconciling your accounting numbers

hours uh check if your client has viewed 00:04:57.199 --> 00:05:02.520 the invoice even pay 00:05:00.199 --> 00:05:07.080 from within fresh books that can be an obstacle Buy credit card so there's no 00:05:05.000 --> 00:05:10.280 excuses for why they haven't paid so if you're Your Own Boss you should be using 00:05:08.800 --> 00:05:14.400 stuff that makes you feel like a boss and freshbooks is an
