How do Koozies work

April 29th, 2008

During picnic koozies are of great use. It acts as a cooler for drinks in the hot summer days. They will keep your drink cooler for a longer time. So you can enjoy a cool summer picnic outside. So we can say that Koozies are the great invention. But did you ever think that how it works? It is simple in design yet it has such a great use. It simply follows the principal of thermodynamic.

As we know that if put cold drinks outside freeze then it comes to room temperature very soon. Same thing happens for hot things also. This is a common phenomenon. This reason helps the inventor of koozies to make koozies. It’s all about the movement of atoms.

For hot items the atoms move in a random motion very fast but in cold condition it move very slowly. Infact in absolute zero degree temperature the atoms almost have very slow motion. During the hot temperature the energy is transferred from source to destination i.e. from hot body to colder body. This process is called conduction. For example when you cook food in frying pan we heat up the centre of the frying fan. The heat doesn’t remain stuck only in the centre position. It get transferred and evenly distributed all over the pan. This happens only because the entire atom move in a random motion and the energy is transferred from one atom to another through collision. So once we turn off the heat it takes some time for the pan to get cold.

Now this conduction principal works for koozies. The material in Koozies slows down the conduction by becoming the barrier between the atoms. Foam is the great barrier. For this foam is used as one of the basic material in making. Koozies get exactly fit over the cans or bottles. Basically the insulation of theCan Coolers work on two principal. First one is the foam should have a plastic cover. The plastic is always a bad conductor of heat which means the atoms can’t get heat from the already energized atoms who are in a random motion. Now the second principal is the foam should have air to circulate. The air is always have been the worst conductor of heat. So air in between the foam will block the heat to go outside or heat from outside get transfer inside. These two principal help to keep the hot things hot and cold things cold. Koozies didn’t allow the temperature of the atmosphere react over the temperature of the can and the bottle.

The koozies not only keep the beer cans or bottle cool but also help to hold the cans and bottle firmly so that drinks do but firmly open split outside. Koozies can also be used also for beverages tea, coffee so that they can be kept hot. You can also keep hot chocolates hot for long time.  Koozies just make an insulating cover over the hot beverage’s can to keep it warm for longer time. It also help you to hold the warm container so that it do not burn your hand. For this griping purpose many people use it to hold cups of hot soups, hot cups for tea and many other purposes
