Official SCP Wiki Information
"Item SCP-294 appears to be a standard coffee vending machine, the only noticeable difference being an entry touchpad with buttons corresponding to an English QWERTY keyboard. Upon depositing fifty cents US currency into the coin slot, the user is prompted to enter the name of any liquid using the touchpad. Upon doing so, a standard 12-ounce paper drinking cup is placed and the liquid indicated is poured. Ninety-seven initial test runs were performed (including requests for water, coffee, beer, and soda, non-consumable liquids such as sulfuric acid, wiper fluid, and motor oil, as well as substances that do not usually exist in liquid state, such as nitrogen, iron and glass) and each one returned a success. Test runs with solid materials such as diamond have failed, however, as it appears that SCP-294 can only deliver substances that can exist in liquid state."
- According to an email from the Site-02 director, SCP-294 was once located at Site-02, but hasn't been returned yet.
