Write the next sentence in this paragraph:

How to make iced green tea 
Boil 4 cups (950 milliliters) of water in a large pot. 
If you would like to make a single serving, boil 1 cup (240 milliliters) of water in a kettle instead and pour it into a mug. 
Take the pot off the stove, and add 4 to 6 tea bags into the water.
The more tea bags you use, the stronger your tea will become. If you would like to make a single serving, dip 1 tea bag into your mug.
