  1. #1&10: Why you never turn your back on the Sea.

    #8: Wonder how much per vehicle that'd be worth?

  2. #7 That would be your Hydrostatic Pressure. Had the front of a house foundation blow out because of it. Heavy rains and no drainage around the foundation. Had to dig down about 10 feet to the footer along the front of the house and down one side so we could repair the block, pour the cells with cement and install a French Drain system. It was a pretty big undertaking.

  3. #3 Cool machine. The added handle for tipping the blocks on end, genius.

      #3 What kind of stone is that? Obviously quite soft from the speed the saws are cutting it.

    2. [rocketride]

      I reckon you're right. I'm guessing those blocks are destined to be salt licks.

  4. Most people don't know that water weighs ~62.5 pounds per cubic foot and suffer the resulting consequences.


    1. In America, a gallon of water weighs around eight pounds.
      So... about eight gallons to a cubic foot?
      I am trying to visualize eight gallon-jugs of water... inside a cubic foot box.
      Forgive me, I was always poor at math.

    2. Amazing but true. 1 cu.ft H2O ~ 62.5 lbs.

    3. Marge, apparently, you know how to type, but decided on not using Duck Duck Go or Google to check. So, I'll help you out:

      The article also provides other information on water for you perusal, including the measurements for calculating the weight of a cubic foot of water from the weight of a gallon of water.

      I've known this measurement since 60's era high school physics class, something you apparently didn't benefit from.


    4. "A Pint is a Pound the World Around..."

    5. A cubic foot equals 1728 cubic inches. (12" x 12" x 12" = 1728)
      1728 cu in / 231 (cu in per gallon) = 7.48 gallons.

      "I am trying to visualize eight gallon-jugs of water... inside a cubic foot box."
      It is deceiving, isn't it Marge?

    6. There are 7.48 LIQUID gallons per cubic foot, as others have already indicated. Actually 7.480519 to be precise. Be aware that the weight of water per cubic foot will vary with temperature, as others have already indicated. Not previously mentioned is, people get in trouble when they look up gallons per cubic foot and find the reference number for DRY gallons per cubic foot, which is different. Ooopsie!

    7. A gallon water jug (plastic milk jug style) is about 6 x 6 x 9 inches, with rounded edges and an inch or so of empty space at the top. Four of these jugs would fit in the bottom of a cubic foot container (12 x 12 x 12 inches). To eliminate the lost space around the edges and tops, pour the jugs out into the container, and it would be filled perhaps 7 inches deep. You can't add another four gallon jugs on top of this, but you could pour in almost 3-1/2 gallons. Total, about 7-1/2 gallons.

      I wouldn't guess this just looking at the gallon jug and the cubic foot side-by-side, demonstrating that the human mind has problems estimating cubic volume. A more common example of this is to put a tall thin 16 ounce glass next to a squat 20 ounce mug; the tall glass looks like it holds more beer. The optical illusion is so strong many people could drink both of them and still think there was more beer in the tall glass!

  5. #3 No hearing protection on either guy. "How many blocks today?" "My socks are fine, thanks."

  6. Found this table on the internet. Not sure about veracity but looks like a cubic meter is over a ton so a wave could have a lot of force.

    Water Weight by Unit of Measure
    Cubic Feet of Water 62.428 lbs.
    Gallon 8.345 lbs.
    1 Ounce of Water 28.35 g
    Liter 2.205 lbs. or 1,000 g
    Cubic Meter 2,204.5 lbs.
    1 pprn 1 lb. per million lbs.
    1 ppm 8.34 lbs. per million gallons of water

    1 pprn

    1 mg per liter of water

    1. Is that heavy water used for nukes or light water :)

    2. One gallon of water = 231 cubic inches.
      That factoid is locked into my memory because I've built fuel tanks for the beds of pickups (I call them 'slip tanks') and have used the conversion to figure out the gallonage of slip tanks that were in company pickups I've driven.

    3. One cubic metre of water is EXACTLY one metric ton. (Here in Oz, we write it as tonne.)

      It's only you crazy Americans that have gallons that aren't gallons, tons that aren't tons, and pints that aren't pints. :)

      It plays havoc when I am cooking.
      Following a US recipe is almost certainly doomed to fail, as all the units are messed up: 1 common use US fluid ounce is 1/128th of a US gallon (29.573+ grams), and that's out by about 4% from imperial measure.
      Then there's the food labelling US fluid ounce of 30 grams, which is over 5% out.
      The dry volume measures of cups etc are the same between US & Imperial, so all the ingredients used in small amounts are out of balance.

    4. Per Willard Bascom, a noted oceanographer, in his book, Waves & Beaches, a three foot breaking wave exerts 3,000 psi on a solid flat surface. His testing involved placing a 12" x 12" flat plate facing the impact zone. The same values were found when placing a steel 3" diameter pipe standing vertical at the shoreline.

  7. #6. Why would someone do that to the kid?

  8. [rocketride]

    #1, #10 "She cleaned up right nice."

  9. Yeah, but if Marge grew up in the 70's and beyond, then she learned the Metric system.

    Plus, of course, "Math is Racsissst". So cut her some slack.....

  10. #8) Oh I want one.....
    #3) OSHA??? don't need no stinking dust masks....
