There are number of ways to lose your voice with some weird and wonderful tactics to implement. Firstly one method you could is to put a tiny pinch of dirt, sand, dry soil on the tip of your tongue. And just before you go to sleep, do not swallow and sleep with your mouth open for the duration of the night and when you get up in the morning your mouth should be all dry. This is because during the night you will have probably swallowed that soil and the grit from this will have scraped your throat, so this way you will have a very croaky voice if not you will have no voice at all.
You could lose your voice another way by coughing up side down for around four to five minutes and then drink some lemonade juice with vinegar to make the throat all crackly.
If that does not work you should scream, say at a big football match or game, or sing loudly for a while until you feel a slight sensation and try to see if your throat is all croaky. But if you do not want to drink water with vinegar and keep it in your mouth then jump up and down and keep your mouth open a night and put vinegar in it and it will work but if any of the things don’t happen to do the trick then have a go at someone and tell them off loudly.
