1. Use the purchased ice box: If your refrigerator has no built-in ice maker, you can buy an ice box in the supermarket or shopping mall, fill it with tap water and put it in the freezer of the refrigerator. Wait a few hours, and you will get solid ice.
2. Use ice trays: Unlike ice boxes, ice trays can be purchased separately and can be reused. You can choose to fill it with tap water and then put it in the refrigerator for curing.
3. Make ice with cold boiled water: If you need to make ice in an emergency, you can put pure cold boiled water in a small plastic bag or ice box and then put it in the freezer. Wait 2-3 hours to get the ice.
4. Make ice with fruit juice or drink: If you want to make ice cubes more interesting, you can make ice with various fruit juices or drinks. Pour the required liquid into a small plastic bag or ice box, then put it in the freezer and wait for a few hours to get ice cubes full of fruit flavor.
Finally, it should be noted that when making ice in the refrigerator, do not open and close the refrigerator door frequently, so as not to affect the ice-making effect. At the same time, the freezer should be cleaned regularly during the ice making process to ensure the cleanliness of its interior.
