	The Food Storage Faq - Specific Specifications
		Using dry ice to displace oxygen from food storage containers is a very straightforward affair.
		Ideally, the dry ice should slowly evaporate and the cool CO should fill the bottom of the bucket, displacing the warmer, lighter atmosphere and pushing it out the top of the container.
		Dry ice may be found at ice houses, welding supply shops, some ice cream stores, meat packers or you could look in your local phone book under the headings "dry ice" or "gasses".

	Carbon dioxide - Wikipedia, the free encyclopedia
		Dry ice is produced by compressing carbon dioxide gas to a liquid form, removing the heat produced by the compression (see Charles's law), and then letting the liquid carbon dioxide expand quickly.
		Tiny pellets of dry ice (instead of sand) are shot at a surface to be cleaned.
		Dry ice is not as hard as sand, but it speeds processing by sublimating to a gas and does not produce nearly as much lung-damaging dust.

	Dry Ice Cleaning - Overview of Icesonic Process
		Dry ice cleaning is a relatively new cleaning process using solid CO2 pellets (known as dry ice).
		Dry ice pellets are made by taking liquid carbon dioxide (CO2) from a pressurized storage tank and expanding it at ambient pressure to produce snow.
		The micro-thermal shock (caused by the dry ice temperature of -79º C), the kinetic energy of dry ice pellets and the air pressure break the bond between the coating and the substrate.

	PACE Dry Ice Cleaning
		The dry ice simply dissipates into the atmosphere after the cleaning cycle is completed leaving only the contamination to dispose of.
		The dry ice pellets are accelerated to speeds up to 300 m/sec by the compressed air and blasted on to the surface to be cleaned.
		Once within the contamination the dry ice sublimes to a much larger volume of CO2 gas, which breaks the contaminatinant away from the substrate and allows it to be blown away.

	Dry Ice and Water
		If the piece of dry ice is large enough to enable the water to cool to its freezing point, liquid water will freeze into a crust of ice on parts of the dry ice surface.
		The reason that putting one chunk of dry ice into a glass of water doesn't freeze the whole glass of water is that more heat is released by freezing a whole glass of water than is absorbed by vaporizing the chunk of dry ice.
		This is made more complicated by the maximum in the density of water at about 4 C. Third, when ice forms on part of the dry ice surface, the ice acts as an insulator slowing the flow of heat from the warmer water to the colder surface of the dry ice.

		A Dry ice bomb is a simple bomb typically made from a plastic bottle, water and dry ice.
		A couple of dry ice cubes are added, then a variable amount of water is added to speed up the sublimation process, the cap screwed on tightly, and the area cleared.
		As the dry ice sublimates to gas the pressure inside the bottle increases to a high enough pressure to rupture the bottle, ranging between a few seconds to a few minutes, varying on several factors including the structure of the bottle, outside temperature, water temperature, and amount of dry ice.

		Dry ice blasting is similar to sandblasting, in a way, in that high-pressure air is used with another substance to remove another unwanted substance.
		In this case the dry ice, or carbon dioxide, is shaved into sugar-size granules and lifts unwanted substances without damaging the surface, like sandblasting.
		There is such interest in the use of dry ice blasting that Silverman is working on an article to be shared with his colleagues about it.

	Howstuffworks "How does dry ice work?"
		A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C).
		Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.
		When you release the liquid carbon dioxide from the tank, the expansion of the liquid and the high-speed evaporation of carbon dioxide gas cools the remainder of the liquid down to the freezing point, where it turns directly into a solid.
