When you drop one of these “Sorting Hat Bath Bombs” in a tub of warm water, it will reveal your “true house.” The bombs start out as a white ball with red, yellow, blue and green stripes.
Once you drop them in the water, they suds turn from white to red (Gryffindor), yellow (Hufflepuff), blue (Ravenclaw) or green (Slytherin), which represent each of the four Hogwarts houses.
