How to make a hollow ice ball

I am usually very surprised when I see hollow ice balls, and wonder how such hollow ice balls can be made? In fact, the method of making hollow ice wine is relatively simple. You need a mold, which can be made into two hollow ice cubes. Finally, put them together to form a hollow ice ball. This requires relatively high refrigeration equipment, and it should be quickly frozen so that it can become a more perfect hollow ice ball.

How to make a hollow ice ball

Make it in two steps. First, make half a hollow ice cube, which is a kind of mold. Freeze into ice cubes, then melt slightly to take out the ice cubes and place the two halves in another ice cube mold. Combine the two halves into one piece and then quick freeze. It becomes a complete hollow ice cube. How to make hollow ice cubes without a mold:

Use a small plastic bag, fill it with water, tie it up with a rope, and then fill it with another piece of water. Fill them up in order and freeze them in the refrigerator. Just tear the bag when you use it. The shape may not be as good-looking as KFC's, but it is basically round! You can try it.

You can also go to the supermarket and buy ice bags, which are bags with grids inside. Fill them with water and freeze them. When you use them, tear the bag open and the ice cubes will be round.

Hollow ice has several advantages over solid ice:

1. Fast cooling of beverages; (the principle of liquefaction of ice cubes of the same volume but different masses)

2. Improved buoyancy (won't block the straw, ice cubes sinking will block the straw)

3. Weak dilution (the drink is too diluted after the solid ice melts)

4. Avoid waste; (solid ice melts too slowly)
