I love taking bubble baths! One of my favorite things to do with my mom is go to the mall and visit a store called Lush. It has SO many bath bombs and bubble bars that smell so good. I wanted to create my own so I came up with the idea for a mermaid bath bomb where the water turns purple, pink, and teal. I thought of ways to make it even better, so I added lots and lots of glitter so it can feel like a super magical bath and make your skin sparkly. I also decided to make it GIGANTIC, because… well, why not?

So here is the tutorial for my DIY Giant Mermaid Bath Bomb. It took me quite a few tries to get it right, so don’t get discouraged. The ingredients are very inexpensive when you buy it in bulk! If you get it wrong the first time, don’t worry, you can still throw it in the tub anyway, go take a bath, and try again later. This is also a great gift idea, perfect for Mother’s Day, Christmas, or any time you’d like to give someone a present you made all by yourself!

You will need:

  • a couple of mixing bowls
  • a whisk
  • teal, pink, purple soap coloring/food coloring
  • soap glitter
    • make sure you use glitter made for soap, regular glitter won’t dissolve and can also hurt your skin and eyes because they are sharp.
  • scented oils in scents you like
  • For each color in the bath bomb, you will need:
    • 1/4 cup (2 oz) of epsom salt
    • 1/4 cup (2 oz) of corn starch
    • 1/2 cup (4 oz) of baking soda
    • 1/4 cup (2 oz) of citric acid
  • water

Step 1:
For the pink batch, mix the epsom salt with purple coloring. For the other colors, I just left it plain.


Step 2:
Mix the corn starch, baking soda, coloring, and scent oils together. Make sure it’s blended well.


Step 3:
Add in a tiny bit of water at a time until it is SLIGHTLY damp and holds together when pressed into a ball. Depending on the kind of color you used, you might not need any water at all. If it is too damp, add a little more of each dry ingredient. When you add the citric acid in the next step, if it’s too wet, it will start fizzing. We definitely don’t want that to happen, so make sure it’s on the drier side.


Step 4:
Mix in the epsom salt, and make sure it’s not too wet. Then add in the citric acid and mix thoroughly.  IF you see any fizzing, add some cornstarch/baking soda and try to get it to stop.  If you mess up, don’t worry, it took me a couple of tries to get it right. (The humidity in the air affects the bath bomb, so it’s hard to give exact measurements.)

Repeat the steps above for teal and purple. In the purple batch, I mixed in a little bit of glitter to make it look even more awesome.


Step 5:
Once you have all the colors, pour some glitter inside the mold and mix it around. Then press the mixture into the mold tightly, alternating the colors however you’d like. Fill both halves and press it tightly together. Let it dry for a few hours. (Once dry, it sometimes comes out of the mold easily, and sometimes doesn’t. You can solve this by putting plastic wrap into the mold first, before the glitter, and it will make taking it out a lot easier.

Once it’s dry, take it out of the mold and let it sit for a while longer (I left it for 2 days) to make sure it’s all dry. Throw it in your tub with your favorite bubble bath and watch the sparkly, colorful, magic!
