bath bomb
Bath bombs are hard-packed mixture of dry ingredients which effervesces when wet. They are also used to add essential oils, scent and colour to bathwater. They are a form of bath fizzies.
==Composition==
Bath bombs' primary ingredients are a weak acid and a bicarbonate base. These are unreactive when dry, but react vigorously when dissolved in water to produce their characteristic fizzing over a period of several minutes; carbon dioxide bubbles on bathers' skin gives a tickling sensation some find pleasant. A common chemical mixture is citric acid and sodium bicarbonate:
C5H7O5COOH + NaHCO3 → C5H7O5COO−Na+ + H2O + CO2
The other ingredients in bath bombs can vary considerably. Most have scented ingredients — such as essential oils — in their composition to impart a pleasant fragrance to the water, and some are brightly coloured. Solid objects, such as glitter, can be added. In Japan, there are usually bath balls, often called Bikkuri Tamago (びっくりたまご ''lit. "Surprise Egg"''). When a Japanese bath ball is fully dissolved, a small object, usually a figure, is revealed. There are many anime-themed bath balls in Japan.
