How do you use a little bit of soap?

In daily life, there will be a small amount of soap left at the end of use. It is a pity to throw it away, and it is inconvenient to continue to use it. You can make better use of it in the following ways.

1 Find a new bar of soap and unpack it.

2 Lather up under the tap with the remaining old soap.

3 Dampen a new bar of soap with water under the faucet.

4 Put the old soap on top of the new soap and squeeze firmly to make them stick together. Then dab your hands with water around the contact surface.

5 Wait for the water on the soap bar to dry and the two bars of soap to stick together. Can continue to use it.

Precautions
Two bars of soap should preferably be the same.
