What is a bubble scoop you ask? Well it is a solid bubble bath. You simply slice, chop or crumble some of the scoop off and place it in a fine tea like strainer and hold it under the running water as you fill your bath. By doing this the water causes enough agitation to the plant based scoop that it creates amazing bubbles. Depending on your tub size and hardness of water you should get 2-4 bubble baths out of one large scoop.
