Rim the Glass (Optional):
Dip the rim of each glass in a little water or fruit punch, then into a plate of sugar to create a sparkling rim.
Prepare the Punch Base:
In a large pitcher, mix the fruit punch, pineapple juice, and grenadine (if using).
Add the lemon-lime soda or sparkling water just before serving to keep the fizz.
Serve in Glasses:
Fill each glass with crushed ice.
Pour the punch mixture over the ice, leaving a little room at the top.
Add the Pop Rocks Magic:
Sprinkle Pop Rocks candy on top of each drink right before serving to let the popping action begin!
Garnish and Serve:
Add a slice of fruit on the rim or float in the punch for a colorful garnish.
