Blown Up, Sir!

I don’t recall how the conversation arrived on the topic, but I was explaining that one could use explosives to tenderize meat to some colleagues recently, and had to go find the story on the interwebs. And so I share with you:

Ka-Boom! A shockingly unconventional meat tenderizer

The idea of bombing meat came to Long some 30 years ago, while he was floating in his backyard pool. A mechanical engineer at Lawrence Livermore (Calif.) National Laboratory, he worked as an explosives expert on the design of triggering mechanisms for nuclear weapons. He was very familiar with conventional explosives and the shock waves created when they go off.

“My body has about the same density as the water,” he observed, “so if somebody threw a bomb into my pool, the shock waves should go right through me.” He started thinking about what those shock waves might do to his muscle — or to a piece of steak. To find out, he recruited friends for an experiment at a privately owned explosives testing site a few miles away.

They sliced a piece of tough beef in two, bagged half of it in plastic, and dropped it into the bottom of a 50-gallon paperboard drum of water. Then they suspended conventional explosives in the water and retired to a nearby bunker. From there, they watched in safety as a television displayed the ensuing detonation.

“The drum totally disappeared. There were just little pieces of paper fiber all over,” Long recalls. The meat, ejected to the side of a nearby hill, was missing for fully 15 minutes.

Once the treated meat had been retrieved, Long cooked it, along with its untreated counterpart, on a grill he had lugged to the site. The unshocked meat proved “so tough you could hardly chew it,” Long says. “But the one we shocked — it was delightful, as tender as a $10 steak in those days.”

This article is a decade old, but Long has been busy. He has several patents relating to the process.

Energy: It's Nothing to Snicker At

Of Car Crashes and Snickers Bars

Pop quiz, hotshot. Using the caloric energy content of a candy bar (e.g. Snickers, at 250 food calories), what is the kinetic energy of a two-ton behemoth SUV traveling at about 70 mph? A first-order approximation is fine — no need to worry about more than one significant digit.

Got it? Think of your number and then proceed to the analysis.

Taking a Whizzo

Making a Crunchy Frog. But if we took the bones out…

Or, how to avoid prosecution for not saying, “crunchy raw unboned real dead frog.”

Since gummy frogs normally come boneless, you’ll have to add them back in manually. It’s a dirty job, but somebody’s got to do it. Conventional confections employ nuts, puffed rice, wafers, or corn flakes for crunch, but these are no ordinary confections: we use Pop Rocks.

An Official Denial. Yeah, That'll Work

Company Denies its Robots Feed on the Dead

In response to rumors circulating the internet on sites such as FoxNews.com, FastCompany.com and CNET News about a “flesh eating” robot project, Cyclone Power Technologies Inc. (Pink Sheets:CYPW) and Robotic Technology Inc. (RTI) would like to set the record straight: This robot is strictly vegetarian.

Sure, it’s vegetarian, now, because you programmed it that way. What happens when it becomes self-aware?

Eat Me Daily

A blog about many food-related things.

A quick note: The name, Eat Me Daily, to some, may suggest something obscene. Get your head out of the gutter.

A secondary quick note: This is not a site for self-proposed “foodies,” and probably not a site for your mom (unless your mom is awesome).

Sunny Side Up

If at first you don’t succeed … Fry, fry again

The Oatman sidewalk egg fry. Cook your eggs, using the sun.

The egg fry began at high noon, with temperatures coming in at 105 degrees at the start of the event, slightly cooler than organizers and contestants would have liked. The spectators, though, were appreciative.

Perhaps the most innovative – and certainly most effective – method of frying eggs on Saturday was that of Eric Schmidt and Xinaxiao Chou from Cibola, Ariz. Using a Frensel lens to intensify the heat, Schmidt was able to cook a perfect – and edible – sunny-side up egg in about 60 seconds.

(Some strange physics commentary, though, about sequestering Carbon.)

(S)Poof!

Another video, reminiscent of the viral popcorn-popped-with-a-cellphone video I discussed a while back

And, in fact one of the response videos is with popcorn

Also one involving toast

Objections: One is electrostatic. Matt has been discussing static charge distributions recently (here and here) and it’s very important to note that he’s discussing charge distributions on conductors — the charges can easily rearrange themselves. But in these video examples, the people and the targets are not conductors. So while you might build up some static charge on a person (in a very questionable display of boys gleefully rubbing other boys with balloons. Not that there’s anything wrong with that, if that’s who you are, balloon-fetish-freaks). A discharge to another insulator just isn’t going to send the energy where you want it to. A small discharge will even out the potential difference, and you’re done. A full discharge needs to be to a conductor, preferably a grounded one.

Speaking of sending the energy, how much energy are we discussing here? I’m not sure how much energy it takes for an eggsplosion, but I’m guessing we’re talking well above a few Joules. Accounting for my slight overestimation of the water content in the earlier popcorn analysis, it probably still takes somewhere north of 10 Joules of energy to pop a single kernel. Can we get anywhere close with static charge?

The energy stored in a capacitor is 1/2 CV^2. The capacitance of the human body is a few hundred picofarads. Let’s be generous and say it’s 2,000 picofarads (pico is 10^-12). How much of a potential difference do we need for 10 Joules? Do the math — it’s 100 kV. A few kV makes for a painful spark when discharging to a doorknob. A 5 mm spark between conducting spheres happens at about 16 kV. A realistic spark leaves us at significantly less than a Joule of energy.

Tasty News

Why taste is as regional as dialect

Prof Taylor said: “Taste is determined by our genetic make-up and influenced by our upbringing and experience with flavours.

“Just as with spoken dialects, where accent is placed on different syllables and vowel formations, people from different regions have developed enhanced sensitivities to certain taste sensations and seek foods that trigger these.”

The part I can’t quite wrap my head around is that this was a test done with British cuisine. One has to question if it is applicable to a broader population.
