The Physics of Zero-G Whipped Cream

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?

Coming soon...

Ah yes, the critical point at which the material is considered both a liquid and a gas...

Horrible how that can remain close to on topic heh.

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.

Yup. My guess is that for most readers, it's not just the space shuttle that's whooshing way overhead.

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.

Just because the effect can be seen in food doesn't mean it shouldn't be studied.

Re:

I guess my question is why this cannot be studied on a vomit comet instead of waiting very precious resources on a space shuttle.

Re:Troll

[Feanturi (99866)]

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.

Re:

[khallow (566160)]

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.

...with only a fraction of a percent of the national budget NASA is making groundbreaking (not being sarcastic) research; Imagine the leaps and bounds they would make with late 1960's percentages.

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

Ice Cream Sundae?!

[Yvan256 (722131)]

An experiment on the Space Shuttle Columbia has been analyzing your ice cream sundae.

I'm lactose-intolerant, you insensitive clod!

Re:

[drinkypoo (153816)]

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.)

I know you were just trying to be funny. Try harder next time :)

Re:

Yes I was trying to be funny, however I really am lactose-intolerant.

Thanks for the information.

Re:Ice Cream Sundae?!

[ip_vjl (410654)]

>> low carb

Not really. Fat is over twice the calories as sugar - removing the sugar would only reduce the calories by about 20-25%.

I don't think that word means what you think it means.

It is a little odd, but it's actually the experiment that is being referred to (unless they've changed it since you wrote that).

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

re: H.Alpert cover

[Ralph Spoilsport (673134)]

1. it wasn't whipped cream, it was shaving cream, which washes off a lot more easily.

2. There were so many delays in getting that cover done, that the model got pregnant. No big deal had they simply gone and done the shoot. But by the time they took the picture she was well into her 5th or 6th month. The more you look at it, the more you'll notice it.

3. It's a fucking awesome record. For those born after 1970 or so, this is how you act like a middle class WASP of the 1960s:
