Clear Ice

It’s Elementary-Right? Making a Perfectly Clear Ice Cube

Making ice is elementary right? The purely magical yet scientifically stable process of changing the state of matter is of course not new but still shape-shiftingly neat and we are still learning the basics, apparently.
So how about making a perfectly clear ice cube? It sounds pretty basic, almost like a harmless junior high school science class experiment, right? Yet it's not exactly basic or harmless.
In fact if you're thinking that you have certainly been able to make clear ice before now, it was quite likely a complete accident-just like all great scientific discoveries are made! Yet unless you are fully equipped with a lot of patience and endless free time with some assistance of using everyday household equipment -you too can achieve the pursuit of the perfect clear ice cube!

The story of 'why' may be equally as interesting as the process itself, so like most science teachers a tangent is included in this lesson on making perfectly clear ice. 
It all started with a guy named Rob Cockerham and a website he started back in 1998 B.G. (Before Google) called Cockeyed.com and it was more of an experiment than a masterpiece or collection of anything. Fast forward to the 21st century and Cockerham's site now occupies at least "800 megs on the internet", is working at Intel, and continues to ask simple questions and providing answers to the mass public as the first unofficial "life hacker" of sorts. 
If you ever wondered how much time a dishwasher actually saves versus hand washing, how to fix a gate or which disposable cup keeps cold drinks cold the longest, Cockeyed.com is a unique and unabashed resource. You may have even heard of his wildly popular series "How Much Is Inside?" which answers questions such as the number of glasses of wine in a regular bottle, how much lipstick is in a tube, etc.. Cockerham finds out the answers to these critical yet quirky questions (think of the $5 foot long scandal for Subway) and shares his discovery in this segment which has been ongoing since 1998!

Now back to clarity or purpose-the task of making perfectly clear ice.

Despite the flood of information on the internet claiming that absolutely anyone can make clear ice, Cockerham proves that the process is anything but as simple as boiling water.
The amateur scientist tried and noted numerous erroneous published claims that if you boil, cool, and re-boil water, the process removes the impurities which make ice cloudy. This double boiling method is supposed to result in clear ice. According to Cockerham, this double boiling process touted by WikiHow for one, is false. 
After over a month of experimenting with more than 15 various methods he just happened to stumble across a photo on reddit of a perfectly clear ice sculpture of Optimus Prime, the notorious transformation shape shifting icon from 'Transformers'.
Cockerham was re-inspired by the possibility of perfectly clear ice after espying this image and asked the poster how such perfection was achieved.  Promptly he was sent the link to an episode of “How It’s Made” from the Science Channel. Their method for creating perfectly clear ice used a constantly running air pump and a large plastic tub of water. After two attempts and days of waiting, the pumping method worked...half way.  Clearly Cockerham is an optimist (not Optimus) and you know what they say his glass (or tub) was half full and not half empty.
After literally sawing off the bad and cloudy, essentially cutting the entire ice block in half, Cockerham was left with a 1 inch thick slab of perfectly clear ice, even “acrylic” in appearance.

So why did he go through this trouble to make perfectly clear ice? 
Besides the obvious celebratory cocktail holder, Cockerham mentioned making “huge ice lenses, craft sweet ice sculptures…” the guy likes to play and do stuff with his hands, and quite honestly clear ice looks really cool.

If Cockerham had just consulted a culinary student first(or find one on reddit)  he would have had perfectly clear ice in less than 12 attempts, (consider the ice sculpture source of inspiration). They teach ice sculpting (often utilizing perfectly clear ice in the design) at most culinary schools. As a curious, hands on, kind of guy, perhaps he could have also learned to cook a new dish with the ingredients in his freezer which are hard to take your eyes off- frozen waffles, chicken, mint moose tracks ice cream, bananas and one pea...ideas? As his clear ice methods fail, the contents of his freezer become more interesting in his pictorial journey, but most significant and a value to us all of course is Cockerhams' conclusion... after a dozen failures, "WikiHow sucks,  and Instructables is unreliable, but the rest of the internet holds great promise."

10 Types of Water & More..

10 Types of Water and More Diluted Truths Water you talkin’ about? Water is of course one of the most basic of life substances on planet Earth. It is the tell tale "sign of life" that astronomers seek evidence of beyond our blue planet. While the significance of water is common knowledge you may be surprised to learn that many people don’t know what 'distilled water' is, or the difference between hard and soft water even. Don't you think we should all know the elementary basics about water? Not just for our own survival but also to debunk or sink all of the diluted truths that are not so crystal clear or don't hold water. 10 Types of Water 1.De-ionized De-ionized water is not exactly ion free , as one may assume. The process of de-ionizing by physicists is called "ion exchanging", whereby the water is passed through a specific resin to eliminate “most anions and cations”. Those are then replaced by combinations of Hydrogen and Oxygen that ...

I do not have a problem with being unique, or should I say not being unique. I mean, I suspect beyond a hunch that I am exactly like many people-most people even-but not all people in more than a handful of ways. I like the uniqueness of others. I am not unique though. I am like many people that are as just different as I am. “I think there’s just one kind of folks. Folks.” Harper Lee Americans love sugar, we even coat our fondest words with it. And fat, we love to chew our fat too. It seems most of us will eat whatever is placed in front of us. I lived in Texas briefly and many, many men (and a few women) called me ‘Sugar’ or ‘Hon’ or ‘Doll’, I only took personal offense with ‘Sugar’ and actually adopted the habit of saying ‘Hon’. Not many people say ‘Hon’ in California, I guess that’s different. Californians don’t actually say ‘DUDE’, not all Californians are actors, athletes, hippies or hobos although we do have these citizens. Most Californians say, ‘it’s all good’ or ‘no wor...

You can’t handle social media

The internet was supposed to make us smarter. Google thinks that’s one of Alphabets main jobs, or they advertise themselves as Information Providers anyway. It’s not working. We are either getting righteously naive or socially inept, or both.  Way back in the early 2000’s, at the peak of my world wide connected optimism about this new democratic, humanitarian, freedom of information age, I taught my toddler how to ‘surf’ and ‘use a mouse’-now that terminology even dates him. On a positive note, he actually did turn out to be really smart. That may be because the chicken came before Google or if you asked the nurses at the hippie hospital he was born in, they would say it was the breastfeeding-but I have proof that’s not it. And that is just it-yes, I said it’s not it, but it is. The amount of misinformation that lingers and spreads, the lies that are let live-it’s not any better with the internet-or smart phones. Proof? Ok, my daughter. As though needed more to be said, still, ...
