I've never done anything like the Floats. They are probably the most monumental-looking, since there's no reminiscence of a container shape. Just because they are so big, the Floats are technically, or let's say physically, the most difficult things that we have ever done. Even though a sphere or a ball is about the easiest form you can make in glass, when you get to this scale, up to forty inches in diameter, it becomes extremely difficult. —Chihuly
