Hi, simple question I hope, so I made the mix added the yeast etc etc but no bubbles etc appeared the next day, so I shook it violently (the only way) and left it, 24 hrs later I looked and it seemed to be motionless so I took the airlock out, put my thumb over the hole and shook.....bad idea, all the air was released and I managed to save any liquid....so I put another pkt of yeast in and have left it alone, is this normal practice for an idiot ? Have I ruined it ? Thanks guys.
