What is a Bath Bomb?

Bath bombs, also known as bath fizzers, are dry ingredients that are designed to effervesce once in contact with warm water. Once it hits the water, it releases essential oils, scents, colors, and bubbles to elevate your bath experience. Bath bombs can help condition the skin and soothe sore muscles. Additionally, they may help detox and relax the body and mind.   The great thing about bath bombs is that they contain the precise amount of oils and bath salts that you would normally have to purchase separately. Not only does using bath fizzers speed up the bath time process, but they make the experience so much better.

Who Invented The Bath Bomb

The bath bomb was invented in 1989 by Lush Cosmetics co-founder Mo Constantine. Working from her shed in Dorset, Constantine was inspired to create her 'Aqua Sizzlers' (which would later become 'Bath Bombs') after becoming intrigued by Alka-Seltzer tablets.[2] While her first attempts looked much like Alka-Seltzer tablets, Mo and her husband Mark Constantine quickly began experimenting with a range of molds and ingredients.

How does a bath bomb work

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. This is an acid–base reaction that involves conversion of citric acid and sodium bicarbonate to monosodium citrate and carbon dioxide:

C5H7O5CO2(aq.) + NaHCO3 (aq.) → C5H7O5CO2Na+(aq.) + H2O(l) + CO2 (g)

The other ingredients in bath bombs can vary considerably. However, most have scented ingredients as well as dye to impart a pleasant fragrance and color to bathwater. Lathering agents, such as sodium lauryl sulfate, are also often added to create bubble foams.

- 400g baking soda
- 200g citric acid
- 200g salt

7. Let the bath bombs air-dry overnight.

8. Once dried, you'll have your homemade bath bombs ready for use.

The tips for making bath bombs

Be sure to use liquid food colouring, not gels. Gels will clump together when you add them to the bicarbonate and it's hard to mix them in.

Once you've added the liquid to the mixture, you need to work quickly to mix everything together and push it into the mould as soon as you can.

To allow your bath bombs to dry, leave them uncovered in a cool, dry place (away from taps and humidity). They will take longer to set in humid weather.

If you've got more than one colour, why not make a rainbow bath bomb? Layer up the different colours and they will blend together beautifully.

How to use a bath bomb:

After the tub is filled with water, take out a product from the gift box. Remove the outer wrap paper and put it into the bathtub. The bath bomb will produce rich bubbles in the bathtub. Then it will float & rotate, dissolve and then become colorful. You can also take bath while the bath bombs is dissolving.
