On a cold winters day, relaxing in a nice warm or hot bubble bath sounds like the perfect way to celebrate National Bubble Bath Day January 8th. Bubbles on top of the water, also known as foam bath or foaming bath, insulate the bathwater, keeping it warmer for a longer period of time. Children find bubble baths fun and enjoy playing with the bubbles which entice them to take baths. Some bubble bath, bath foam or foaming bath serves a dual purpose and can also be used as to wash skin and hair.
