Product review (5 stars): Once I find the best method for this there are many other things to try to make.
I had to use these a few times before I could make the perfect round ice ball. The first time I filled them, I must have been too cautious, because I ended up with a half globe. But if you are slow and patient : seal the two halves and s l o w l y fill it through the hole. Then be careful setting it in the freezer! Fortunately, the bottom half is heavier and flat bottomed to avoid tipping. When they are nice and frozen, good luck getting them apart!! Again, fortunately, you should only have a bit of bother freeing your ice sphere the first or maybe second time you use the molds. Don't think you need to run it under water. All you need to do is gently work your way around slightly prying the two halves apart. Now that I've used them countless times, I can pop them apart easily. Once I find the best method for this there are many other things to try to make ice ball out of.
