Giant bubbles on Stinson Beach

A step up from what we did as kids.

The rainbow colors come from interference between light waves reflecting off the inner and outer surfaces of the soap film. This interference produces light of different wave lengths: colored light.

Learn how to make them here.

    It looks like an enormous jellyfish about to eat the kids.

    I wish there were a decent aquarium near me.

      I am sure there are plenty of other things out there prepared to eat children!

        Catholic Priests, for one.

    Now that is cool.

    Wow! But that is technical progress.

    And you knew this was coming: a nitpick. Interference “produce” light in the same way that evolution “produce” traits. It is the constructive and destructive interference of light weakly trapped in thin films that produce interference colors from infalling daylight. Wiki saves me from detailing, that link gets the gist.

    Thin film production can give you, say, silicon dioxide coats on silicon wafers that are even enough that you see only one of those interference colors to satiety. Color overload!

    A step up?
    Understatement of the year. Like having a pet elephant rather than the pet mice we had!

    It is beautiful, but it reminds me of the giant bubbles that would recapture escapees from The Village in The Prisoner.

      It’s been a while since I’ve thought of Rover. Too bad the ending of The Prisoner series was so over-the-top.

      One of my favorite episodes was called, I think, “Many Happy Returns,” where #6 is allowed to escape home only to be taken back on his birthday.

    Ah Stinson beach. Horrible drive to get there and you can’t get in the water because it’s a feeding ground for white sharks…

    Bay Area folks without wetsuits finally have a good reason to go to the beach!

    I’m just glad my 2-year old is still impressed with our 1-inch wide bubble wand. I can still be the amazing dad for a little bit longer…

      Note the absence of swimsuits or even short sleeves. It must be summer there.

    Their death is almost as beautiful as their birth.

    (But if you’re going to start Toccata #1, you have to finish it, not cut out just before the pedal-point. Show the footage again, if need be.)

    How do you find this stuff? … This is really trippy.

      As the h/t “Finder” I have to admit that I saw on on The Guardian website. They have a weekly viral video chart with this kind of nonsense on. Today’s parkour cat video also came from there…
