When washing with a bar of soap, there comes a point at which it just gets too thin to be used. The common solution is to press the remains onto the outside of a new cake.
Sadly, this usually doesn’t work well (at least without Herculean levels of compressive force being applied -which, with slippery soap, is quite a challenge).
Today’s invention is a way to overcome this minor issue and also appeal to the increasingly frugal buying public.
It consists of a slot moulded into each bar of soap (always a favourite marketing tactic, to reduce the volume provided, per unit cost).
When that bar has been mostly washed away, it’s remnant can be inserted into the wedge-shaped recess provided in a new bar, making their amalgamation much easier.
