Rule #1 : no wetting including washing & swimming 5 days before putting a perm in it. Chances are the chlorine would still be in your hair and will react to the perm chemicals and result in hair loss and or the perm will not take to your hair. Also no wetting 24 hrs prior to applying the perm or the chemicals will not take to the hair and it woukd be a waste of time.
Why must the stopper at the top of the separatory funnel be removed before liquid can be withdrawn through the stopcock?
If the stopper is left in place while liquid is draining a vacuum will be created in the separatory funnel and outside air will try to get in. The only way it can do this is through the opening that the liquid is trying to leave. The air pushes against the liquid and will greatly reduce or even stop its flow. If the stopper is removed no vacuum is created because the air can easily get in the top of the funnel.

Wetting the bed on purpose?
If someone is wetting the bed on purpose it means they are consciously allowing themselves to urinate while they are aware of what they are doing. as to how to start there is a mental barrier in place, kind of a "i have been told not to do this" kind of thing.
