Mad Scientist Invents Colored Bubbles

Anonymous Custard writes "Popular Science has a fascinating article up about toy inventor Tim Kehoe's quest to create colored bubbles. 'Chemical burns, ruined clothes, 11 years, half a million dollars--it's not easy to improve the world's most popular toy. ... It turns out that coloring a bubble is an exceptionally difficult bit of chemistry.'"

      I did some experiments trying to create nitroglycerin when I was 17, but later I learned that the nitric acid sold commercially contain chemicals that inhibit the reaction (the bastards!). Maybe the guy found a way to inhibit the inhibitor?

To do this, you need to work with a mixture of nitric acid and sulphuric acid + SO_3.

      Kehoe made a bubble like that when he was 26, after only two years of trashed countertops and chemical fires. He showed it to toy-company executives, who called it a "holy grail." And then it broke, as bubbles always do. And when it did, the dye inside escaped onto clothes and carpets and walls and skin, staining everything it touched.

As with Kehoe's first bubble, it arose from the slow, subtle refinement of a process over thousands of experiments. But Sabnis could re-create it. He synthesized a dye that would bond to the surfactants in a bubble to give it bright, vivid color but would also lose its color with friction, water or exposure to air--not fade, not transfer to something else, but go away completely, as though it had never been there. When one of these bubbles breaks on your hand, rub your hands together a few times and look: Poof. Magic. No more color. If the bubble breaks on your shirt or the carpet or the dog, you have two choices: Dab it with a touch of plain water to remove it immediately, or forget about it for half an hour. Either way, the color will soon be gone.

      Sabnis's solution was to build a dye molecule from an unstable base structure called a lactone ring that functions much like a box. When the ring is open, the molecule absorbs all visible light save for one color--the color of the bubble. But add air, water or pressure, and the box closes, changing the molecule's structure so that it lets visible light pass straight through. Sabnis builds each hue by adding different chemical groups onto this base.

There's a toothpaste that would turn kids' mouths a bright color until they had brushed for the requisite 30 seconds, and a soap that would do the same for hand washing.

    He's also thinking outside the toy chest, mucking around in the lab on weekends making things like a Swiffer that leaves a momentary trace showing where you've Swiffered and a temporary wall paint that would let you spend a few hours with a color before committing to it. The dye's reach is so great that there are even biotech and industrial uses being discussed. "We've got stuff in the works I can't talk about that'll blow bubbles away," he says excitedly. It might take years, but, knowing Tim Kehoe, we'll see them eventually. After all, it's only a little extra work."


    But anyone who thinks entertainment and fun are not important and/or not business-worthy is living a lonely, sad life on a different planet from this one.

    After ten years of almost entirely unsuccessful tinkering, he got some financial backing and finally employed a guy with a PhD. in dye chemistry to work on the problem - who apparently cracked it by synthesising an unusual molecule called a 'lactone ring' - something Kehoe would never have created in a lifetime of messing about in the kitchen.

    The '11-year quest' makes a nice story, but it was an actual scientist who created the bubbles. Props to Kehoe for the idea, but he didn't have the skills to realise it.

      Strangely if you read the *entire* article they also mention that were it not for his tinkering the dye chemist would've created a wonderful way to create colored bubbles that had nothing but a spot of colored dye on the bottom. He DID contribute a great deal to this effort - distributing the dye evenly over teh shape of the bubble...

  104. Shelf Life, Toxicity, and Safari Innovation... by Anonymous Coward · · Score: 0

    On the pink, blue, yellow, and heliotrope surface, colored bubbles based on the chemistry they describe seem like an amazing toy. However, I'd be willing to bet that the bubble solution has a mediocre to poor shelf life, especially after being opened, assuming the colors fade with exposure to air, heat, etc. Oopsy...or maybe cha-ching!

    Maybe Kehoe Bubble Jedi Master will vacuum-pack the solution and/or use stabilizers - seems likely. However, unless cash-fisted bubble wielders are prepared to use up all of their solution within a short time, they may find that the only colors they see are on the cool, plastic packaging of their ZGen-hip, anthroblowmorphic, bubble bottle characters. The more solution they use, the more air will accumulate in the packaging, and the worse the problem will become, conceptually not unlike my esteemed, dried-up glue bottle collection.

    Maybe they could repurpose the famous Pokemon marketing slogan as: "Gotta blow 'em all!" Who knew that this Hudsucker-esque success of simplicity might become the ultimate porn industry sex toy!?

    On the up-side, if the solution does fade, it will be no worse than run-of-the-mill bubbles, unless of course there is some as yet undetermined toxic effect of all the various lactone compounds they are using to achieve the slippery soap spectrum. We must consult BOB, the Bubble Oversight Bureau, or at least the FDA.

    Despite my burgeoning product concerns, it's hard not to be inspired by the success of the Fabulous Bubble Boys and want to run right out and buy or seek to imitate their product. The dye chemistry involved is a great achievement.

    Personally, I am about to embark on a 20-year mission to create "Safari Bubbles," also known as "The Hairy Grail." These are bubbles that form in surface-area-to-volume-ratio-defying animal shapes with iridescent safari print colors, which then sprout synthetic fur as they slowly drift over the suburban savannah. Rowr! Hmmm...maybe I can make them solar-powered and capable of playing mp3 animal noises! Eureka!

    Tomorrow, I plan to go to all the regional zoos and buy one of every animal to blend up in my sink. Who needs scientists?! I may destroy a few kitchens, and the elephants may crush my dining room table and collapse the foundation, but thank God I have a Vitamix! With luck, success will be mine if the tigers don't kill me first.

  106. Well he had drive and managed to get money by TheLink · · Score: 2, Insightful

    True it was the Indian chemist who did the final version of the bubbles (quite impressive work too - managed to do it within a year). I think few chemists would be able to do that sort of thing.

    But this guy had the idea, AND the persistence, AND the luck to get the financing.

    Otherwise the Indian chemist might be doing other stuff rather than bubbles.

    So what if you're brilliant AND have the idea, if you can't get any money to pull the idea into reality, the idea just stays an idea.

    Or if you're brilliant, but you have no ideas in that particular field. While you might be able to think of millions of ways of creating dyes (which might impress chemists in other fields), but that's different from thinking of things that could impress kids and toy manufacturers.

    Without that particular team of people, there wouldn't be these coloured bubbles.

    And interesting dye tech too.

    Does it by absorbing light though.

    I wonder if they can make bubbles which have intense iridescent colours. While normal soap bubbles do already get colours from iridescence, they don't really have intense colours. You might be able to also have something that washes away easily or that is fairly transparent - after all it probably won't be a "normal" dye - it'll be thin layers of transparent refractory stuff.

  108. easy for any dye chemist by bodrell · · Score: 1
    I realize I'm in a rare position, being an employee at a company whose biggest business is organic dyes, but do a google image search for "coumarin" and for "lactone." See any similarities? A lactone is far from being an unusual "molecule" (it's a functional group, really--a cyclic ester; contrast with lactams, such as the penicillins, which are cyclic amides).

    Coumarin is one of the oldest known fluorescent compounds, and is the base structure for at least 100 dyes, I think it's fair to say. Coumarin comes from the decomposition of lavender, and its relative, coumadin, is a very common blood thinner. When horses eat rotten lavender (mixed with hay, usually) they start bleeding internal as if they'd eaten rat poison.

    I don't understand what took this guy so long. One of the oldest ways to monitor surface tension of water (i.e., evaluation of different soaps / surfactants) is to see how much soap it takes to solubilize a greasy, red dye. A dye like that is going to stick to the hydrophobic tail of any surfactant, not fall to the bottom of the bubble in a small, colored dot. On the other hand, the optical properties of a bubble are a lot different from those of a solution, so a red dye might not make a red bubble. Regular soap makes rainbow-colored bubbles, with no help from any dyes.

    Greasy aromatic rings are generally required for color absorption, so most chromophores (the basic dye molecule) are already hydrophobic, and attaching a long, hydrophilic tail (PEO, polyethylene oxide, commonly used to solubilize hydrophobic drugs so they'll have a longer circulatory half-life) would be trivial for any chemist. It doesn't take a PhD, or even a pH meter.
