|Examine||A cup of water.|
A Cup of water is an item made by using an empty cup on a water source. Using a bowl of water on a stove then using it on the cup will create a cup of hot water. Cups of water cannot be heated using a fire. This item is solely used to make a Guthix rest potion. A cup of water cannot be used to counter the desert heat effect because the water in the cup evaporates under the heat.
