Product Overview: With the Ice Ball you can forget about drinks ending up watery and warm because the ice cubes have melted too quickly. The Ice Ball will melt evenly as you drink.Traditional ice cubes will cool your drink initially but soon start to melt leaving you with a warm watered down version of your favourite tipple only halfway through your drink. The ice ball melts at a much slower rate as it is one large solid clump of ice, keeping your drink chilled to the end with minimal dilution. Depending on how fast you are drinking and the room temperature one ice ball could last for several refills. How to use the Ice Ball mould Put the two mould pieces together so you have a ball shape. Fill the mould with water using the hole on the top of the mould. Being careful to keep the mould level to avoid spilling the contents. Place it in the freezer on a level surface and leave undisturbed until frozen. Once the ball has completely frozen you can seperate the two parts of the mould and release your ice ball. If you have problems getting the ice ball out of the mould run it under a little cold water and try again. You can then store your ice ball in the freezer for later use or use it immediately.
