The Physics of Zero-G Whipped Cream 80

SpaceAdmiral writes "An experiment on the Space Shuttle Columbia has been analyzing your ice cream sundae. Or, rather, it looked at the phenomenon of 'shear thinning,' which explains why whipped cream comes out of the can like a liquid, but sits atop your sundae like a solid. The experiment actually involved shear thinning of xenon, a substance used in ion rocket engines, but whipped cream tastes better." I'm not sure it was cost effective to fly Herb Alpert & the Tijuana Brass into low earth orbit either, but hey, it's NASA — who am I to judge?

      Good thing they had the wisdom not to go with their original album title "Sheer Thinning and Other Delights". I think it was Zorba the Geek that gave them that advice.

      Well, that brings back a memory.

      Whipped Cream was one of the first albums I remember my Dad playing when I was a kid. He gave me his old bongo set (yes, bongos... this was the '60s, after all) and I'd play along with drums on the more upbeat tunes like "Peanuts".

      Back on topic... There could be lots of uses for this new info about shear-thinning. The article mentions improved motor oils and better liquid plastics. I've read that this research could apply to better wall adherence for paints, and othe

        C'mon, *everyone's* dad had that album. Mine included. He was actually a Herb Alpert fan so the album cover was just icing on the cake.

        So to speak.
        • Yeah, my Dad was a big Herb Alpert fan back then. Still is. He asked me to transfer all of his LPs to cassettes so that he could listen to them anywhere in the house or in the car. I suggested that he just buy them on CD, for the convenience factor plus the higher fidelity. He looked at me like I'd sprouted another head.

          You can't change some people, and no use trying to bring them into the modern day. So, I did as he asked. Now, every time I go to my parents' house, he's playing those Herb Alpert c

        By measuring how strongly the fluid resisted the movement of this paddle, the experiment could determine the xenon's thickness. CVX-2 searched for changes in this thickness as it slowly changed the speed of the stirring and the temperature of the fluid.

        My guess is that they needed to keep constant freefall for more than just a minute or so at a time.

        I suppose, if we were rational about it, we'd have developed a second generation reusable launch vehicle in the wake of the Challenger accident in 1986 and discontinued the Shuttle sometime in the early 90's.

        Well, that's exactly what happened in the 60s. They had this big space race with Russia, and had to prove they were better than the "commies". This means they got well funded, and the people working for NASA had a lot of motivation to do a good job. Currently there is no real incentive for NASA to show anyone else up. In 1961, just a few months after the first human was put in space (by the commies) Kennedy said they would have a man on the moon, and return him safely by the end of the decade. And they

      Real Ice Cream (not ice milk, or ice-milk-and-cream) has almost no lactose in it. Practically no one makes the stuff, of course. Buy an ice cream maker, and make your own. you won't save any money but the stuff will be dramatically better. It's also low-carb if you use a substitute for sugar (I like Splenda/Sucralose.)

      • Why would there be almost no lactose in cream? There is still plenty of water in cream, which is what the lactose is dissolved in, up to 50% less than milk perhaps ... but 50% less doesn't equate to almost none IMO.

        Unless you want to use sour cream in your ice cream I don't see how it could have almost no lactose.

      Speaking of the Columbia, I found this quite interesting:

      Most of the data from the experiment, called Critical Viscosity of Xenon-2 (CVX-2), was beamed down to scientists on the ground before the shuttle's destruction during reentry into Earth's atmosphere. Remarkably, the hard drive from the experiment survived the disaster and was found amid the wreckage, and technicians were abl

There are other cans of whipped cream that are just fine, typically containing cream, sugar, nitrous oxide, vanilla (usually fake), and often some starches or seaweed polymers. Some are made with heavy cream, some are made with light cream and more polymers (and maybe some powdered dry milk as well.)
