Soap Cubes

Go ahead, wash your hands with these pastel ice cubes--they're actually soaps made using a plastic ice cube tray as a mold.

Things you need

Block of glycerin/liquid food coloring/petroleum jelly/cotton swabs/and a microwavable container

Directions:

Glycerin is usually sold in large blocks; to melt it cut it to a size that will fit in a microwavable bowl or measuring cup.

Smear a dab of liquid food coloring into the bowl or measuring cup with a cotton swab.

Heat the glycerin on high stirring at 15 second intervals, until it's completely melted. Use a cotton swab to coat the inside of the ice cube tray with petroleum jelly . Pour the melted glycerin into the tray, filling each section almost to the top. Cool for about 2 hours;the soap cubes will pop right out. Like cubes of ice, they'll also melt-getting gradually smaller as each pair of hands is washed
