You will need : 1 cup of lemon juice, 1 cup of sugar, and 6-7 cups of cold water.
Cut the lemons in half, then squeeze in a dish so you have 1 cup of juice.
First, get a small pot, put 1 cup of sugar, and 1 cup of water in the pot.
Put on medium heat until the sugar is dissolved.
Pour the lemon juice in with the sugar water and let it cool.
After letting it cool, get a jug of any kind (but clean!), put 5-6 cups of cold water in and then pour the lemon mixture. Place in the fridge.
Drink and ENJOY!!!
