Supplies Needed:
fruit -- whatever kind you like (except no bananas); make sure it's good and ripe for maximum sweetness and flavor. I like to use all kinds of citrus and berries. I also found pineapple and watermelon to work well for flavoring water. If you don't want to buy whole ones, many grocery stores sell small containers of pre-cut fruit.
herbs -- these are optional, but many herbs are a surprising complement to fruit flavors; almost any herb will work depending on your personal preference
jars or pitchers -- I use 2 quart mason jars primarily, but any 2 quart pitcher will do.
fruit infusion pitcher--I recently purchased one of these--it's another option if you think you'll be making infused waters regularly; a very easy, tidy way to strain fruit from water.
fruit infusion water bottle--I love using this for a portable, on-the-go option.
muddler or wooden spoon for mashing fruit and herbs
water -- I use filtered water, but regular tap water is fine if yours tastes good to you
