Making Bath Bombs

Updated on August 1, 2013

Make Your Own Bath Bombs

Making bath bombs is not rocket science, but bath bombs rock.

If you've never had the pleasure of bathing with a bath bomb, well, let me tell you, they're great! Some bath bombs fizz (they're also called bath fizzies, go figure) and are especially fun. When the bath bomb hits the water, it fizzes and tingles your skin. Bonus!

Make your own bath bombs. It's easy! The hardest part is rounding up what you'll need. There are lots of "recipes" out there, but I'll give you a few easy ones plus lots of links to check out other bath bomb making recipes.

Note: These are not bomb bombs. They are bath bombs!

Bath bombs fizz from the simple chemical reaction between an acid and a base.

What are the ingredients in bath bombs

that cause this reaction?

Acid = citric acid

Base = baking soda

Bath Bomb Recipe - Simple bath bombs

Here are the ingredients you'll need to make bath bombs. The first four ingredients are the dry ingredients. The remaining are wet ingredients. (Just telling you since that's how I'll refer to them later. Got it? Got it!)

  1. 1 cup baking soda
  2. 1/2 cup citric acid (don't worry, there's a link below to order it and everything else here, if needed)
  3. 1/2 cup cornstarch
  4. 1/2 cup sea salt or mineral salt
  5. 3/4 tablespoon water
  6. 2 teaspoons of essential oil for fragrance
  7. 2-1/2 tablespoons light vegetable oil, like light olive oil or almond oil
  8. 1 or 2 drops of food coloring

Be Sure Your Molds Are Ready To Go

Have your molds at hand.

When mixed, you need to get the

bath bomb concoction into the molds quickly.

Mix Up the Bath Bombs

Use a plastic or glass bowl (not metal because some ingredients can react to the metal) and mix all of the dry ingredients together.

That would be the baking soda, citric acid, cornstarch, and sea salt.

Next, in a small glass or measuring cup, mix the wet ingredients. That's the water, essential oil, oil, and food coloring.

Slowly pour the wet into the dry and mix them together. Go slow and only pour a little at a time so it doesn't foam up.

Mix with your hands and when all of the liquid is incorporated with the dry, the consistency should be kind of like wet sand, but not too wet.

Fill the molds (spread a towel on the table to catch dribbles of the "sand mixture" that will escape the molds).* Be sure to pack the mixture in very tight.

Two-part molds (like the plastic eggs I used) can be opened right away to release the bath bombs. The molds don't have to sit long. Gently unhinge one side and let rest a minute. Then let the bath bomb fall into your hand by holding it upside down.

Molds that are open, like ice cube trays, need to air dry at least overnight to harden.

*Then shake the towel into your bath water later!

Bath Bombs Need to Air Dry

Let the bath bombs air dry at least

overnight or for several days.

If you use a silicone mold, let the bath bombs dry completely in the molds before removing them.

For two-part molds, you can

release them right away.

Molds for Making Bath Bombs

You can use just about anything to mold the bath bombs: ice cube trays, muffin tins, candy molds, plastic eggs, little food containers like what individual-sized dressing comes in, you get the idea.

There are also lots of molds to buy too. Here are a few.

Bath bombs work best in warm

or hot water (not cool water).

Add dried flower petals or herbs

to your bath bombs.

FYI: It's fun but makes bathtub

clean up a little messy.

      Your bath bombs are beautiful... thanks for the recipe! I've been looking for a new craft... and even though these are popular I didn't know about them until just now.. because I live in the boonies. There's nothing like this in the stores around here.

      This is a new one for me, not heard of them before. But we take showers now. With bad knees, hard to get in and out of tubs.

      I didn't know you could make bath bombs - what a fun activity! Maybe I could get the kids to make the bath boms, and I could just test them out.
