A supermarket research institute in Salt Lake City, Utah, USA has recently developed a self-cooled beverage can. from
Since the massive use of top open cans in 1962, this may be the first breakthrough in can manufacturing technology.
The interior of the self-cooled can has a small box filled with pressurized carbon dioxide gas. When pulling the lid on the sheet to open the can, a release valve connected to the sheet releases the pressurized carbon dioxide gas inside the box. When the gas is released, Its volume expands rapidly, causing a sharp drop in temperature. The released gas is quenched from the capsule to minus 60 degrees Fahrenheit and the temperature of the food in the can is lowered by about 40 degrees in 90 seconds.
Newly-developed beverage cans will reduce certain canned containers when used to hold beverages such as beer or soda, because the pressurized CO2 gas cartridges make up 1.5 ounces per 12-ounce can. Naturally, its cost will also increase by 5-7%. However, the research organization believes that the convenience that such cans will bring to people is self-evident.

The ideal size for a small running bag is 30 liters, which is big enough to hold the ten essentials and extras for a personal climb. running bag can be as small as 10 liters or as large as 40 to 50 liters. If you are a frequent leader or carry a teammate (or a child), you may need a running backpack of 40 liters or more. In most cases, a travel backpack capacity of 30 liters is a standard capacity and the most popular choice. But if your activities range from hiking in summer to skiing in winter, you may need more than one shoulder backpacks. Consider your needs to determine your shoulder sling bags choice.
