It's really easy to make great soda pop. You can start with any beverage but try a fruit juice concentrate from the grocery store. They make the best soda pops!
All you have to add is the dry ice. For a party, make a big batch. (That's a 15-gallon insulated jug above.)
And you can make luxurious soda floats with your new soda pops. Pour it over ice cream and then drizzle it with a dessert sauce or ice cream topping.
