    The Great Sand Debate! (or, Does Sand Wear Out?) With pics!

    Yea, a provocative title - sorry...

    While I don't have one of them fancy new modern smart phones that can take pictures of a single grain of table salt, I do have a microscope! And and old digital camera. And, by carefully holding my camera over the eye piece of the 'scope, I was able to take the following 50x photos of new & used filter sand. (Well 50x in the 'scope. Probably several hundred times magnified as displayed.)

    So, can you tell which are which, old -vs- new?

    Left pics are "Set 1". Right pics are "Set A".

    Bonus Pic!
    Just for fun - a picture of my microscope and phone with a picture of my microscope and my camera with a picture of a slide on the microscope...

    Yep...and if you had a picture of that sand from a million years ago and a pic of that same sand a million years from now, they would all look the same...but thanks for the visual demonstration!!

    I know - but a picture says a million-years worth of words!

    ETA: Plus, I got to play with my microscope for the first time in 30+ years!
