A bath bomb is a great way to enhance your bath time experience. They are usually made primarily with baking soda and citric acid that together give off a fizzing experience. Many other additional ingredients are added to give a foamy, skin conditioning, or colorful bath art experience.
A bubble bar is similar to the bath bomb adding fun to the bath, but produce mainly bubbles. Instead of the product in a liquid form it is solid. You may have seen that they are cut in ASMR style videos and added with other bath products to give mounds and mounds of bubbles like a bubble bath cocktail. They are best used in a strainer or bubble basket to help dissolve the solid particles under running water. The disruption from the running water the more it produces bubbles.
