Mini Bubble BombsHow to use: Add the mini bubble bombs to your bath once it is full. We recommend using at lease 12 cubes to gain the skin softening benefits of the mini bombs, but feel free to use as many or as few as you want in a single bath. Ration them and use just a few or indulge in the luxury of adding the whole bag just for fun! Seriosuly though, we use 1 2 a bag or less in our baths, and if it's for our little ones, usually only a handful of cubes.
