Thank you for your questions about collecting cans souvenirs!!

Due to the characteristics of the material made of the can, some parts of the can (especially where the bottom of the can touches the table) will naturally break after a few years of storage, resulting in the leakage of the liquid inside. Therefore, the body of the can used for collection must be removed from the liquid.

There are many ways to remove the contents inside, the easiest is to open the pull tab and pour it out, but this will affect the appearance. As Songleo said, some people will drill holes in the bottom to make them remain, but most of the cans in China can be solved by a more ingenious way, which is to turn the ring horizontally at an angle, and then drill a hole under it to pour water, and finally return the ring to its original position. That's perfect.

However, in fact, some people can make it last for a long time without doing any treatment, that is, using the method of "crystal sealing", wrapping the body of the can with some special transparent materials, which feels like a can stuffed into jelly. However, there are many people who oppose this method, believing that it loses the meaning of collecting.

I think it's good to fall off, because after a long time, there is gas in the coke, which will cause the can to swell after a long time. Cans may. bang ！！

Poured out, of course, you have to understand that you're collecting cans, not cokes.

1. Pull the tab of the Coca-Cola can and drink the drink, and the empty bottle is easier to preserve. 2. Use nails to make two small holes symmetrically in the inner ring at the bottom of the Coke Coke aluminum can, and then release the cola drink. 3. Turn the tab tab of the Coca-Cola can to the hidden place, then make a hole next to the dot on the tab and release the Cola drink.

Note that after draining the water, be sure to rinse the bottle and can with clean water, otherwise the bottle and can will stink and corrode the tank. When the bottle is dry, wipe it clean and wrap it in plastic wrap.

Canned drinks also have an expiration date, so you should keep the empty cans after drinking.

After turning the ring to the left (or right), use the hollow drill to hit the small eye, release the drink, and then return the ring to its original position and cover the hollow.

Cans should be selected without bumps, and those that are deflated should not be wanted.

Addendum: There is an article on page 8 of the 66th issue of China Philatelic News this year, which says "......It is better to use an electric drill, millimeter drill bit. Once you've drilled the hole, quickly find a place to shake the Coca-Cola can vigorously, and the Coca-Cola will spew out.

At the end of the spray, the gas runs out, and there will be a little in the can, at this time, you can use hot water to flush the bottom of the can, and the Coca-Cola inside will be completely cleaned. ”
