Hidden Black Bath Bombs (Halloween idea)

I’m a little late to the black bath bomb party that has been happening all over Pinterest, Instagram and You Tube.

Because it’s been done before, I never felt like I could add anything new by turning it into yet another DIY.

But then this thought popped up in my head: what if you can’t SEE it’s a black bath bomb? What if it’s a black bath bomb in disguise? What if I took the black bath bomb to a whole new level of creepy?

First it starts as a pretty rose petalled bath bomb. But as it fizzes the black starts to ooze out from the sides, leaving a trail of darkness behind.

Because of the difference in proportions between the mini bombs and big bombs they also start to move around in your bath water. Like they are haunted or something.

Watch it spin!

Creeped out already?

Make black mini bombs

The idea is to make a smaller bath bomb to fit into a larger bath bomb.

Combine the citric acid, baking soda and corn starch in a bowl.

Dilute a few drops of black soap (or food) coloring in 1 teaspoon of oil. I used almond oil.

I actually didn’t have black coloring. But when I was trying to make purple for my DIY Unicorn poop bath bombs I found out that if you combine red and blue it actually turns a murky black.

So for this DIY I diluted a few drops of red and blue coloring in a teaspoon of almond oil.

Slowly add the oil to the mixture. Stir well until combined.

At this point my bath bombs turned a very, very dark emerald green/black. Next time I’m going to experiment by adding green and orange coloring to the mix.

For extra drama you can add activated charcoal. I added 12 capsules in total. This really intensified the blackness of the bombs.

A word of caution though: activated charcoal definitely leaves a residue in your bath tub. So you will need to clean your bath tub after you’ve taken your bath. If you don’t like the sound of this, you can easily leave it out.

Put about 1 tablespoon of witch hazel or water in a spraying bottle. Spray the mixture and stir well each time. Do this until the mixture starts to clump together.

To make sure the bath bomb will float, scoop some of the mixture into both sides of the mold instead of pressing it down. Make sure both sides are overflowing. Next, press both sides firmly together to form a bath bomb. Set aside to cool.

Give the mini bombs time to set and dry. I actually left them overnight just to be sure.

Make the big bombs

Now for our big bomb that fits over our black mini bombs.

Combine the citric acid, baking soda and corn starch in a bowl.

Again, put about 1 tablespoon of witch hazel or water in a spraying bottle. Spray the mixture and stir well each time. Do this until the mixture starts to clump together.

At the bottom of the bigger mold I put a few dried rose petals.

Start filling in your mold with the mixture pushing it to the sides. This way you create a hole for the mini bomb. Kind of like an egg in a bird’s nest.

Put the mini bomb in the middle. Scoop some of the mixture in the other side of the mold until it’s overflowing. Press both sides together so the mini bomb is completely locked in.

Let the bath bombs dry and set overnight.

These make the Ultimate surprise gift for your Valentine or a perfect Anti Valentine treat for yourself!

    Hi – love this tutorial! I make soap and bath bombs, but I’ve had a couple of folks say that the bombs stain their tub and skin. I use the same coloring for both products. Have you had any trouble with staining? And would you mind sharing what kind of soap coloring you use?

    Thanks so much!!

      Hi Lori, I’ve used both soap and food coloring from different brands and I’ve never experienced any staining! Maybe you used too much oils or butters? The only thing I can think of is that the colored oil sticks to the edges and makes it seem like it’s the colorant staining the bath tub. I hope this helps!
