OK. This has to do more with chemistry than words, but the words I quote below have bothered me now for one whole day and I need some help here, so, if you understand chemistry or related areas, I will be very appreciative for some explanation.
I read:
Using dry ice to displace oxygen from food storage containers is a very straightforward affair. To prevent leaching plastic chemicals from the container into your food over a long period of time I recommend lining the bucket with a food grade plastic, mylar or brown paper bag before filling the bucket with your product. Be sure to wipe any accumulated frost off of the ice and wrap it in a paper towel or something similar so you don't burn anything that comes into contact with it. Put the dry ice at the bottom and fill the container. Shake or vibrate it to get as much density in the packing as possible and to exclude as much air as you can. Put the lid on, but do not fully seal it. You want air to be able to escape.
Here's my confusion over the above linearity, which loses me just about every, single time. You're putting food into some kind of container, right? You're lining that container, say, with mylar, as suggested, right? That's to keep the plastic from leaching into the food. That makes sense. But why do you wipe the accumlated frost off the dry ice? What big deal difference would it make to have a little bit of carbon dioxide frost on the dry ice? You're going to wrap the dry ice in a paper towel anyway, so what's the deal about wiping it off?
I know this doesn't have to do with any particular word, so I hope you won't mind my bringing this up, but I am very puzzled over these directions above.
Thanks for any help here over this frosty query,

Parbly wouln't make a difference if it were carbon dioxide frost. Onliest thang it's parbly dihydrogen monoxide frost an that stuff's deadly.

So, if it's the parbly dihydrogen monoxide frost (read, "deadly") that's the problem, why wouldn't the paper towel (or something stronger) solve that problem?
And, while we're at it, if you spray carbon dioxide out of a cylinder across a table top, does it really roll across the plane and then fall off the table like a waterfall? Is this true, as my daughter's boyfriend told her last night, or is this a case of a teenage boy trying to pull the wool (waterfall) over a gullible girl's eyes?
Best regards,
DoubtingDub

Try it sometime and see for yourself.
Ya gots ta get up perty early in the afternoon to pull my wool over the ice.

Dear Faldage,
I do not have any cylinders of carbon dioxide around here, so I can't try the experiment, though I would love to see carbon dioxide waterfalls, I must admit.

Don't s'pose that wool would be any protection against that parbly dihydrogen monoxide deadly frost, would it?
Best regards,

Dear WW: The instructions tell you that the food will keep better if oxygen in excluded. The solid CO2 evaporates, and the CO2 gas pushes air containing oxygen out, and refrigerates food. It warns you not to have solid C02 in contact with food, which could cause "freezer burn". If there were a lot of moisture in the air, it might condense on the solid CO2, and much later when solid CO2 is gone make a puddle that might contaminate the food.
Seems a lot of work and expense ;for a mere bucket of food.

I once used the phrase the dry ice bins in a poem, meaning ice bins that were empty and dry, but it read as bins for dry ice. So I had to put a hyphen in ice-bins for clarity's sake. And if you were intending the other meaning, bins for dry ice, I guess you'd have to put a hyphen in dry-ice. Dry ice bin(s) without a hyphen seems to be semantically-challenged, it just can't stand alone. Ah, the quirkiness of the English language!

or is that Cole Porter?No, no DubDub, a colporteur is a guy who runs around selling bibles. Now if you're talking about some cold Porto, I'll be right over with my glass.  You can go to a bicycle shop and obtain - for about twenty bucks - a tire inflater that uses carbon dioxide cartridges. So, you can do the waterfall experiment AND have a way to pump up your bike tires quickly, AND stop an assailant in his tracks by yelling, "Freeze, sucker," then uh, well, freezing him.

Dear Geoff,
You bring the cold Porto, whatever that is, and I'll get the cartridge, and we can wax poetic over the waterfalls.
Best regards,

Egads!! A word-related post?? How dare ye? Good point on your dry ice bins; and excellent solution. Was the hyphen your idea or your long-suffering editor's?* ~~~ * Not to imply WO'N's editor would be any more challenged than any other. All editors are long-suffering. Trust me on this one.
