Tip: Soda machines dispense sugar-free carbonated water
Topic:Soda machine
When you push the main lever on a soda machine, it gives you soda, right? 
However, if you observe closely, you'll notice a smaller lever to the left of the main one.
Pressing this smaller lever will dispense just carbonated water. This feature is present in many machines.
