Baking soda, or sodium bicarbonate, has the chemical system NaHCO3. In water, baking soda rapidly dissolves, and the positively charged sodium (Na+) breaks other than negatively charged bicarbonate (HCO3-). [Goopy Science: How to Make Slime with Glue]

In the meantime, the citric acid additionally dissolves, with a single hydrogen ion (H+) separating from the remainder of the molecule, Wooden-Black stated. Then, that positively charged hydrogen from the citric acid and the negatively charged bicarbonate from the baking soda mingle, in a short time present process a sequence of reactions. One of many finish merchandise is carbon dioxide (CO2). As a result of carbon dioxide is a gasoline, it kinds small bubbles within the tub water, creating a pleasant fizz.

Troubleshooting DIY Bathtub Bombs:

  • In case your bombs are too moist you’ll be able to add extra baking soda. 
  • In case your bomb is crumbling and never staying collectively, add extra moist elements. Do that rigorously. You may fill a sprig bottle with water, witch hazel or alcohol and spray your combination to make sure you don’t add an excessive amount of water.
  • If the bomb fluffs up you’ve added an excessive amount of liquid or added liquid too quick.
  • If the bomb is tender, it wasn’t packed down sufficient or it was too moist.
  • If the bomb has bumps the moist and dry elements weren’t blended properly sufficient.
  • If the bomb cracks down the center, it was not molded correctly. I heard that when you shrink wrap it and wait 24 hours, it can come again collectively.
  • If the bomb sticks to the mildew the combo was too moist.
  • If the bomb doesn’t float, it’s more than likely not dry sufficient. Bombs can typically take a number of weeks earlier than they’ll float.

More often than not you’ll be able to crumble up the bomb right into a bowl and tweak the combination. Not all is usually misplaced when you make a mistake with tub bombs! Don’t throw it out simply but!


As an alternative of coconut oil, be at liberty to make use of olive oil, almond oil, avocado oil, castor oil and so forth.

I wish to omit cornstarch in my subsequent batch and am considering of utilizing coconut milk powder as a substitute. From all that I’ve researched I’m certain it can work nonetheless, I haven’t tried it but.

So long as you retain the proportions of liquid to powder and don’t omit baking soda or citric acid, you’ll be able to mess around with elements to be able to obtain completely different advantages and reactions out of your bombs.

Add it to your dry combination. Butter will soften in a sizzling tub and provides additional nourishment for dry pores and skin!
  • You may separate a batch into a number of smaller batches, add completely different shade to every batch and layer the completely different colours to make a beautiful tub bomb!
  • Utilizing a tablespoon to indent insides of each halves of the mildew then fill the indention with one other coloured batch of tub bomb combine in order that whenever you use it, a shock shade is inside. 

Whereas I had a tough go of constructing tub bombs because of the flimsy plastic molds, I’m planning to purchase the right metallic molds and experiment extra. I discovered a Youtube channel known as Artistic Bathtub Lab and she or he is the queen of all issues bath-especially tub bombs. She makes essentially the most artistic excellent tub bomb each time!
