Unabill writes “An inexpensive “Soda Fountain Pro” toy from Target is converted into the agoraphobic alcoholic’s dream gear: a home-use Bar Gun. With two buttons on the gun, this enables you to automatically dispense any two-beverage combo. This project requires a CO2 system – making it the perfect add-on project for someone already outfitted with a kegerator. Dispense shots like a madman, mix drinks while you are dispensing them, or even use it for (gasp) actual soda dispensing.”Link.
