Every time you unscrew the cap of the soda maker, during those few seconds when your fingers are hanging on the press button, do you always feel a bit nervous in your heart? Press three times to avoid the bubbles being too weak, like drinking plain boiled water with added air. After pressing it five times, I was afraid of hearing a “hissing” sound, and then this can of CO₂ would be empty in just a few days. In fact, you are not the only one struggling with “the number of presses” – the vast majority of soda maker users cannot avoid the question “how many pushes per tank of co2 for soda maker”.
