Without a doubt, National Lollipop Day on July 20 is a day that children of all ages can celebrate. We’re looking at you, grandparents — relive some childhood memories! People in the Midwest call lollipops suckers but they go by other names as well — lolly, or sticky pop. They come in many flavors but mostly fruit flavors for licking or biting. Lollipops are made of flavored sucrose, water, and corn syrup that are hardened on a stick.
