For a kid's birthday party in the summer, this is a nice drink to serve in hot weather: an Icy drink. This is a great idea, in which you can add a variety of flavors to glass, so every time you drink you will taste something else.
Prepare your lemonade by mixing ½ cup orange syrup with 3 cups of water.
Pour it into the ice cube tray.
Freeze at least 8 hours.
Take the cubes out of the tray and put them into a plastic freezer bag or container.
Repeat this for the blackberry syrup and grenadine.
By using different types of fruit syrup and lemonade you get a different taste in your glass every time you drink.
Due to the large number of ice cubes you have to make, it is wise to start at least 3 days before the party by freezing the ice cubes.
To get ahead of time, you can take all the ice cubes out of the ice cube trays or plastic ice cube maker bags and put gather the cubes in a large plastic bag, so you can easily distribute them to the glasses when it's party time.
