Save soap from dispensers
If you wrap a gum over the donor neck of the soap, you can not push your head all the way down, saving you a lot of soap. It is often the case that you push out more than you need at all.
You can also use this method with creams with a donor. When the soap is almost all, you release the gum again. Especially for families with children, it makes sense, because children push much more often on the head and, however, need much less.
