Summarize the following:
Let it sit out until the temperature of the water is roughly the same as the room's temperature. You can use your finger to test the water's temperature. The time it takes your water to cool depends on how hot or cold it was when you poured it. Room temperature water tends to mix better with ginger and lemon. Pour the lemon juice from earlier into your glass of water. Use a spoon to stir the mixture until the lemon juice is thoroughly mixed in. Pour the grated ginger into your water. Use a spoon to mix the ginger until you have an even mixture. You can now drink your ginger water. If you want to cool your beverage, you can add ice. Ginger water generally lasts for about a day after mixing. If you don't finish your water right away, store it in the fridge overnight.
Pour a 12-ounce glass of room temperature water. Add the lemon juice to your glass. Mix in the ginger. Store the water in the fridge. Finished.
