Everything’s better with ice cream! Ice cream sodas are undeniable proof of that. Ice Cream Soda Day is a day to celebrate the delicious cold drink in the summertime. This beloved combination, also known as an ice cream float, was invented by Robert McKay Green in 1874. He originally created the float because he ran out of ice and needed a way to make his drinks colder. From this point on soda parlours everywhere began serving ice cream sodas and they became popular with generations of young people. You can celebrate this holiday by going to a traditional ice cream shop or simply by making an ice cream soda on your own by mixing ice cream with a soda flavor of your choice.
