First pour the water in a medium sized bowl or pitcher
Next cut the two lemons in sixths with a sharp knife. ( Make sure not to cut yourself!)
Squeeze 5 of the lemon slices in the water. Then, mix with a spatula. After, pour the ice in the bowl or pitcher and mix. Finally, pour the mixture into a glass or pitcher and put the remaining lemon on the side of the glass or pitcher like the picture. Enjoy!
