  • If the 300m people lived in the same area and you got a true random sample.

    Sunsets at 9:09 today in Michigan

    Sunsets at 8:04 today in California

    Sunsets at 8:34 today in North Carolina

    Sunsets at 7:57 today in Alabama

    Sunsets at 7:38 today in Arizona (They are on standard time)

    Sunsets at 7:13 today in Hawaii

    Sunsets at 11:36 today in Alaska

    Someone in Arizona might want the sun to set at 7:38. It’s blazing hot all day.

    Someone in Michigan might be fine with sunsetting at 8:08 with standard time.

    Someone in Alabama might not want the sun to set at 6:57.

    Someone in Hawaii probably doesn’t want the sun to set at 6:13.

    Even if you split up the 1000 people to equally represent all states, that’s only 20 people per state.






  • Yeah, they can weigh up to 2000lbs with a king-size bed. A king-size bed is 6,080 sq in.

    A fridge can weigh 300lb being 36"×30". 1,152 sq in.

    Fridge is .26 pounds per sq inch. A water bed is .33 pounds per sq inch.

    So while heavy the weight is distributed basically like a fridge. This is assuming an empty fridge.

    As for durability, a quality waterbed mattress is thick. You aren’t going to pop it or cut it without deliberately trying to.

    Even if you took a knife and stabbed it from the top, it’s not going to leak until you put weight on it.


  • That’s a misconception for water beds.

    High-quality water beds have stabilizer pads in the mattress

    The idea of the old crappy 70’s water bed where they slosh around is a poor idea.

    You aren’t laying on a ziploc bag barely filled with any water.

    It’s more like a ziploc bag filled with molasses. If I pushed a corner down it would slowly bring up everywhere else. If I stopped pushing a corner it everything would slowly go back down.

    Say I have a massive gut and sleeping on my right side. I’m displacing X amount of water. If I was to turn to my left side I am still displacing the same amount of water. Just the empty space that use to hold my gut would be filled with the water from the other side where my gut is now. Someone on other side of bed wouldn’t even feel it because the water underneath them doesn’t change.


  • This is why water beds are amazing

    Winter you put memory foam to keep you from the cold water, in summer you sleep on the cold water.

    Only downsides to a water bed are: 1. Heavy 2. You have to add chemicals to your mattress as regular maintenance 3. It can’t really be extra firm (but a lot more firm than people think)

    The water will steal every bit of heat from your body, but you’ll stay warm with a blanket

    Good take

    I wouldn’t even be against sharing some information so they could give me better ads

    I’m not in the market for a new car. I don’t need car ads.

    But knowing I shop at Something Hardware a lot and they are having a spring black friday sale on the tool I’ve been eyeing would be nice.

    Even still Something Hardware just slapping their logo in an ad is not helpful at all.

    If ads were helpful they wouldn’t be annoying

    your freezer at -18 °C (0 °F) or lower. This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C (140 °F) where bacteria can grow quickly.

    According to Canada.ca

    Every 2 F is basically 1 C. You have more whole numbers with F.

    Like -15°C is 5°F

    6°F is -14.4444°C

    -14°C is 6.8°F

    So 5, 6, and 7°F are about equal to -15, -14.5, and -14°C.

    And it’s not just a random number. You know how much more energy would be used if everyone kept their freezer just a couple degrees colder? It’s the optimum recommended temperature.

    USA uses US Customary units, not Imperial units.

    Fahrenheit is grouped with US Customary units but is not one.

    I agree metric system is superior and there isn’t a reason to use Inches, Feet, Yards, etc.

    But Fahrenheit is a great system for weather and works great for everything else.

    For science if I have to heat a beaker to 280° it doesn’t matter if it’s C or F. I’m not going to be able to relate to 280° in either system. The instrument is going to have to tell me the exact measurement.

    Same with like a tape measure. I can measure out 3 meters. I don’t need to know how long 3 meters is to do that.

    However, mark two lines on a piece of paper and I will get closer guessing in inches than cm because I know the US customary units better.

    Eventually US will change to metric. But I doubt we will ever not use Fahrenheit for normal day things like weather

    When do you use 0° and 100°C?

    This is also at standard pressure and most do not live at sea level.

    I don’t put a thermometer in my water to make sure it is boiling or one in my water to make sure it freezes.

    It can snow and roads can ice before it hits 0°C

    It has no real world applications

    90-110 is hand washing temp. 100 average.

    110 is hot

    120 recommend max

    130 very hot

    140 very very hot

    150 burns

    If I said to you. Would you stick your hand in 50°C water for 100 dollars would you do it?

    What about 60°C?

    65°C?

    I bet you don’t know what would happen if you stuck your hand in 65°C water without looking it up. There’s a huge jump from 60° to 65°C. 70°C will instantly scald you.

    Someone out there is stupid enough to think. Water boils at 100°C, 65 should be perfectly fine. Even though water doesn’t boil until 212°, most people would be cautious of sticking their hand in 100°F+ water.

    Yes if you think 40°C+ is hot then you can gather that 65°C would be hotter. But why compare to 40° when you can do 100°.

    Not sure where you got -4F from.

    USDA, United States Department of Agriculture, recommends 0°F or -17.8°C

    100°F in the shade isn’t extreme, and you’d be able to survive normally (With more water, everyone can use more water)

    100°F is hot tub water

    120°F is recommended hot tap water

    140°F water will pretty much burn you instantly

    0F is the temperature a freezer needs to be to keep food fresh.

    50F is the point that you can’t survive without clothes, your body will not generate enough heat.

    100F (38C) will not burn you alive. You can survive for a long time in a sauna at 200F.

    100F is perfect hot tub temperature
