Use glycerin and your favorite character to make a soap that looks like a rubber duckie (or any other character).
What you need
1 bar of glycerin soap (usually yellowish and transparent)
A soap mould or other suitable container Like
a small round plastic container
A plastic rubber duck
Begin by melting the block of soap down in a double boiler method.
Pour the soap into the mould and submerge the rubber duckie half in and half out.
This will make it look like its sitting in water and looks really cute.
You can add food coloring and fragrant oils just prior to pouring into the mold.
Try using other toys like spiders and bugs.
