Pour peach Schnapps into shot glass. Add chilled cranberry juice to fill. The origin of the Airhead.... We do not know whether this drink already exists, but one night we decided to experiment. Erika and Heather were at Erika's empty house (litterally) preparing for a party. After many shots we came up with something that we both enjoyed. Combining our names Er-Hea-d : Airhead. Enjoy!
