An idea to end soap bar waste by simply changing its usual shape. I´ve proposed this idea to Unilever and they reject it; they know nothing!
1. When a soap bar is ending, you have three options:
a) Throw away de remains
b) Try to make a mini-soap ball/sausage compressing the pieces whit your bare wet hands
c) Try to attach the remains to a new soap bar
2. Problems with this options are:
a) You throw away usable soap,
b) You have to constantly keep preasure on the new mini-soap to keep it thogether and
c) It will fall, always
3. So the solution is, ta-da...
A simple shape change will allow a new one to be filled with the remains of an used one. And after a few uses, works just fine!
