00:00:00,199 --> 00:00:07,560
water two simple hydrogen atoms merged with a single oxygen one to create the

2
00:00:05,080 --> 00:00:12,840
harbinger of all life in the universe it is Earth's most precious resource but

3
00:00:10,480 --> 00:00:17,199
it's also the substance most responsible for ruining our favorite outfits

4
00:00:14,879 --> 00:00:21,119
electronics and parades since the very beginning of time and that is why

5
00:00:19,320 --> 00:00:26,880
waterproofing techniques have been on the Forefront of technological advances

6
00:00:23,599 --> 00:00:28,599
since well technology was invented and

7
00:00:26,880 --> 00:00:33,320
although nature provided us with rudimentary water protection in the form

8
00:00:30,480 --> 00:00:37,440
of tree branches and caves it quickly became apparent that we needed to

9
00:00:34,920 --> 00:00:42,879
protect our warm-blooded selves and tribemates from the harsh thermal

10
00:00:39,840 --> 00:00:44,960
robbing effects of constant drenching

11
00:00:42,879 --> 00:00:50,000
these evolving forms of water protection came to be measured by their ability to

12
00:00:47,360 --> 00:00:55,640
resist humid and damp conditions known as damp proofing or their ability to

13
00:00:52,640 --> 00:00:57,920
resist water infiltration known as

14
00:00:55,640 --> 00:01:02,160
waterproofing now water and dampness resisting techniques usually involve

15
00:01:00,280 --> 00:01:06,840
covering an object with something that will help it to repel liquids the

16
00:01:04,519 --> 00:01:11,400
original Scotch Guard treatment from 3M is a great example it was used on

17
00:01:08,920 --> 00:01:15,680
furniture and clothing inherently porous materials to resist water penetration

18
00:01:13,479 --> 00:01:19,720
and prevent stains from spills but modern science has taught us that just

19
00:01:17,479 --> 00:01:24,200
because we can doesn't mean that we should and the fluorocarbons used in the

20
00:01:22,119 --> 00:01:28,560
original formulation of this product were capable of causing liver failure

21
00:01:26,079 --> 00:01:33,360
and birth defects so new techniques needed to be developed both to overcome

22
00:01:30,560 --> 00:01:38,280
those downsides and in response to new demands like that uh PE repelling wall

23
00:01:35,960 --> 00:01:42,399
paint that causes public urinators to accidentally soak their pants and shoes

24
00:01:40,119 --> 00:01:46,520
or bringing it back somewhat more on topic the developments in the protection

25
00:01:44,200 --> 00:01:51,119
of electronics where they originally turned to cumbersome physical barriers

26
00:01:49,000 --> 00:01:55,479
that either prevented or impeded their use but have thanks to Modern

27
00:01:53,079 --> 00:02:01,680
Technologies like the 2013 development of nanomaterial coating 1,000th as thick

28
00:01:59,360 --> 00:02:06,159
as a human and hair are now able to protect Electronics by just covering

29
00:02:03,640 --> 00:02:11,560
them with this tiny layer that forces liquid molecules to bead and roll off of

30
00:02:09,160 --> 00:02:15,239
surfaces without penetrating them allowing for things like the new

31
00:02:13,360 --> 00:02:19,920
waterproof mobile devices that we've seen with some relying on rubber

32
00:02:17,239 --> 00:02:24,640
barriers for Extra Protection but others leaving exposed their headphone and

33
00:02:22,080 --> 00:02:29,000
power Jacks they're going be back but these methods also aren't the Beall and

34
00:02:26,879 --> 00:02:33,879
end all of waterproofing techniques and whatever a manufact urer may claim the

35
00:02:31,879 --> 00:02:38,680
best way to prevent water damage is still to keep your stuff from getting in

36
00:02:36,519 --> 00:02:43,200
contact with water which is why waterproof headphone Jacks often still

37
00:02:41,440 --> 00:02:48,440
have a little Rubber seal at their base and serious waterproof items like

38
00:02:45,680 --> 00:02:53,200
Pelican hard cases usually follow the old steadfast method of encasing an item

39
00:02:51,280 --> 00:02:57,239
in something durable and then tightly sealing it in which carries the added

40
00:02:55,000 --> 00:03:02,239
benefit of decreasing an object's vulnerability to higher water or

41
00:02:59,840 --> 00:03:07,840
atmospheric pressure often measured in numbers atmosphere with each digit

42
00:03:04,560 --> 00:03:09,840
representing 10 m of depth with the only

43
00:03:07,840 --> 00:03:15,200
disadvantage to this technique being that it also restricts access to a

44
00:03:12,319 --> 00:03:20,080
container's contents and anyway unless total submersion is the plan more often

45
00:03:17,560 --> 00:03:25,200
than not water resisting techniques combined with our final waterproofing

46
00:03:22,120 --> 00:03:28,239
strategy controlling and routing fluids

47
00:03:25,200 --> 00:03:30,560
around is amply effective you'll see

48
00:03:28,239 --> 00:03:35,720
this method used in the over flow port on your bathtub on your house in the

49
00:03:33,040 --> 00:03:40,239
form of a waterproof roof and gutters to keep liquid from pooling and penetrating

50
00:03:38,040 --> 00:03:46,080
and even in lenovo's water rerouting ThinkPad keyboard which can survive a

51
00:03:42,799 --> 00:03:49,840
direct spill on top of it but that's the

52
00:03:46,080 --> 00:03:52,040
key to all of this I guess a spill just

53
00:03:49,840 --> 00:03:55,439
because an item is rated for a general type of water protection and you can

54
00:03:53,519 --> 00:04:00,519
learn more about these standardized ratings up here that does not mean that

55
00:03:57,879 --> 00:04:06,360
it will stand up to prolonged or extreme exposure cases like rugged water sports

56
00:04:03,519 --> 00:04:10,400
or adventures in the salty blue sea there's a big difference between

57
00:04:07,920 --> 00:04:14,720
long-term Solutions and protective measures so just because that new phone

58
00:04:12,319 --> 00:04:18,759
is rated at safe to however many meters or whatever that is not an invitation to

59
00:04:16,880 --> 00:04:23,080
make dropping it in the toilet a morning routine especially for coffee drinkers

60
00:04:21,400 --> 00:04:27,440
speaking of morning routines it sure is hard to get up in

61
00:04:25,360 --> 00:04:32,720
the morning if you stayed up all late reconciling your accounting numbers and

62
00:04:30,240 --> 00:04:37,120
you know logging your hours for jobs no no no forget about that freshbooks is

63
00:04:35,000 --> 00:04:41,639
the online accounting tool that is designed for freelance workers or small

64
00:04:39,240 --> 00:04:46,919
businesses it makes invoicing getting paid and tracking your expenses easier

65
00:04:44,560 --> 00:04:50,800
and helps you get organized little details about cash flow are all in one

66
00:04:49,000 --> 00:04:54,880
place so you know where you stand and you can see a full history of each

67
00:04:52,600 --> 00:05:00,199
invoice allowing you to uh log your hours uh check if your client has viewed

68
00:04:57,199 --> 00:05:02,520
the invoice even pay

69
00:05:00,199 --> 00:05:07,080
from within fresh books that can be an obstacle Buy credit card so there's no

70
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

71
00:05:08,800 --> 00:05:14,400
stuff that makes you feel like a boss and freshbooks is an easy way of doing

actual difference in performance from one card to another in spite of them

80
00:05:46,880 --> 00:05:52,199
