Give the water a chance to cool down until it’s warm before you use it to make your ice.
If you want clear ice cubes, just get a mold with a square-shaped tray instead.
Ice ball molds may work differently depending on the brand, so always double-check the instructions that came with yours.
Set a sphere mold on top of a short thermos with a diameter just smaller than the mold. Fill the thermos up with water and put the sphere mold on top so the hole is submerged in the water. Open your freezer gently while you’re making clear ice balls since sudden sharp movements can cause bubbles to form in the ice.
If you have trouble pulling the mold out or apart, try running some cold water over it to help loosen the ice. If there’s ice sticking to the bottom of the mold, just knock it off the excess with a wooden spoon. Be careful not to hit too hard so you don’t crack the ice balls.
