To create the diagonal stripe, tilt the pop during freezing so one corner is lower than the rest of the pop. The root beer and cherries will slide to that corner, creating a colorful stripe.
Alternate Soda Ice Pops:
Black Cow Float Pops: Before chilling the root beer in step 1, stir in 1/3 cup chocolate syrup.
Egg Cream Float Pops: Replace the root beer with 2 and 1/2 cups seltzer and 1/3 cup chocolate syrup. When you add the ice cream in step 3, pour in 1 and 1/2 cups milk along with it.
Cream Cooler Float Pops: Replace the root beer with cream soda.
