How can you freeze ice without ice?
If we find that there is no mold at home when we want to use frozen ice, we can find out if there is any unopened jelly at home, then open the jelly and squeeze it out, clean up the remaining jelly shell, and finally pour water into the jelly shell to freeze it.
Or we can find out if there are any small cups similar to burning wine glasses at home, and then pour water into them to freeze them, but these quilts are hard in texture and it may be difficult to take out the ice cubes after freezing.
If we can't take the ice out of the cup and the mold, we can put it indoors and let it stand for a while. When the ice melts a little, it will naturally fall off, or we can apply a hot towel to the cups and molds.
