Who’d’a thunk it?

  • Good Signage Seems Difficult

    As expected, the mis-assembled cart corrals in the Walmart parking lot remain that way. One corral has an additional feature that’s surely been there since Day 0:

    Walmart cart corral - backwards and upside down
    Walmart cart corral – backwards and upside down

    On the upside, that’s a high-reliability, high-availability trash can.

  • Cast Iron Pan Electrolysis: Anode Fragment

    Sacrificing a scrap EMI shield from a junked PC as the electrolysis anode, I grabbed a tab with the battery charger clamp:

    Cast iron pan electrolysis - bucket
    Cast iron pan electrolysis – bucket

    Turns out it didn’t survive the encounter:

    Cast iron pan electrolysis - anode front
    Cast iron pan electrolysis – anode front

    That white blob extends around to the other side:

    Cast iron pan electrolysis - anode rear
    Cast iron pan electrolysis – anode rear

    Yeah, it got hot enough to melt a blob from the 6 gallon plastic bucket before burning through.

    I tossed that into the garage so I wouldn’t forget it aaaand here we are …

  • Mother In Law’s Tongue Plant: Flower Season

    Both of us began sniffling and sneezing in early October, long after the outdoor flowers faded away, and finally remembered to check the Mother In Law’s Tongue:

    Mother In Law Plant - flowering
    Mother In Law Plant – flowering

    It’s that time of the year again: we’re both wildly allergic to a houseplant with weird flowers. Even after cutting the stalk off and deporting it outdoors, we’re still sniffly.

    The blossoms produce so much nectar that the droplets near the base of each flower eventually fall off, making a mess on the floor if the stalk tilts over far enough.

    We kept it when we helped Mom move out of the Ancestral House, long ago, and it’s still going strong.

  • ATM Error Message

    Saw this after fat-fingering my PIN at a drive-up ATM:

    ATM Screen Display Error Message

    That’s off-putting, isn’t it?

  • Monthly Image: Hawk vs. Squirrel

    A hawk, perhaps an immature Red-Tailed, landed on a branch outside the kitchen window while we were eating lunch.

    After a minute or so, a squirrel ran up the maple and began taunting (?) the hawk:

    Immature Red-Tail Hawk vs. Squirrel - approach
    Immature Red-Tail Hawk vs. Squirrel – approach

    The hawk obviously had no clue what’s going on inside that critter’s little brain:

    Immature Red-Tail Hawk vs. Squirrel - faceoff
    Immature Red-Tail Hawk vs. Squirrel – faceoff

    The squirrel alternated between inching out on the branch, closer each time, and dashing back to the tree trunk, for maybe ten minutes. It eventually reached the rightmost patch of lichen, a foot from the hawk, without suffering any damage, after which it ran down the tree and away. We have no explanation.

    Perhaps this is the same squirrel as before? All we know: (over)confidence goeth before gibbage.

    Taken with the DSC-H5 near the end of the adventure; it took me a while to deploy the camera. The first picture looks diagonally upward from the kitchen, through three layers of 1950-era glass. The second comes from the back door, zoomed about 10x, with no tele-adapter. Obviously, good color correction didn’t happen here…

     

  • Pi Measuring Tape

    This clearly demonstrates that the world is even more weird than I imagined (clicky for more dots):

    Pi Tape
    Pi Tape

    I don’t measure that many big cylinders that I can’t figure out their diameter by hand.

    The prices suggest folks who need Pi Tapes need them bad.

  • Monthly Science: Time-release Pills

    I left a time-release melatonin pill in water for a day:

    Time-release melatonin - 24h water
    Time-release melatonin – 24h water

    Perhaps an acidic environment would be more to its taste?

    Here’s another pill after a day in vinegar:

    Time-release melatonin - 24h vinegar
    Time-release melatonin – 24h vinegar

    In both cases, poking the somewhat dissolved pill separated it into gummy chunks, so it’s probably working as designed. I suppose the usual stomach churning would help.

    This being a quack nostrum, there’s no way to tell what’s inside or how much you’re getting, but I didn’t expect to get way more B6 than you’d expect from the large print on the label. Lesson: always read the fine print, no matter how well it’s concealed.

    0/10 – would not buy again.

    As before, the results do not differ significantly from placebo, so this is a triumph of hope over experience.
