Making a round ball of ice is something anyone can do. This is a fun project for children as well as adults who are young at heart. All you need is a few supplies that you may already have in your house.
Instructions
1. Take a round balloon of any size and fill it with water from the sink. You can fill it up as much as you like, but keep in mind that the bigger it is, the longer it will take to freeze. You should also be sure that the balloon will have enough space in your freezer.
2. Let all the air out of the balloon. If an air bubble remains inside the balloon, it will cause a large dip in the ice ball. Tie the balloon once the air has been released.
3. Put the balloon in the freezer. If you have a round bowl that is about the size of the balloon, you should put the balloon inside it. This will help the balloon keep a round shape during the freezing process. You can freeze it without putting it in a bowl, but the ice will end up being flat on one side.
4. Let it freeze for at least one day. A large ice ball could take up to three days. A balloon the size of a softball will be ready in one day and a balloon the size of a basketball will take three.
5. Take the frozen balloon out of the freezer. Take a knife and carefully make a slit in the balloon. If the balloon doesn't easily peel away from the ice, run it under warm water for five seconds.
