The 11 Year Soap Bubble

-Overdrive- writes "Popular Science has an interesting article about an inventor and his 11 year quest for Colored Bubbles" From the article: " It turns out that coloring a bubble is an exceptionally difficult bit of chemistry. A bubble wall is mostly water held in place by two layers of surfactant molecules, spaced just millionths of an inch apart. If you add, say, food coloring to the bubble solution, the heavy dye molecules float freely in the water, bonding to neither the water nor the surfactants, and cascade almost immediately down the sides. You'll have a clear bubble with a dot of color at the bottom. What you need is a dye that attaches to the surfactant molecules and disperses evenly in that water layer. Pack in more dye molecules, get a deeper, richer hue. Simple. Well, on paper anyway."

    Just goes to show that it is easier to make duplicate stories than coloured soap bubbles.

    ... that whenever there is a dupe, there are people like the above posters telling everyone that it is a dupe. In reality, their comments are merely duplicates of previous posts. If duplication is really an issue for you at slashdot, either:

    a. attempt to become a staff member
    b. submit some non duplicated content.

    halfway down this preachy tirade, I realize that someone already has probably told the dupe police here that what they are doing, is in fact, duplicating duplicates. So I find myself dubiously duplicating the disasterous duties of other dupe police dislikers.

    FFS, talk about the article, say something funny/insightful/etc, or troll around to waste time at work. I'snt that why we come to /. anyways?

    OT: Hope that didn't burst anyone's bubble :)

    Because they're obviously testing us, man. You see, right now the dupes are pretty damn easy to see, but eventually the dupes will get harder to spot and the stakes will get higher. Those who don't point out the dupes will be eliminated and the ones who point them out get lower numbers. In the end, there will be one person and he will be crowned King of Slashdot, and he will get girls. And touch their boobies.
