I love a good bath at the end of the day and so does my youngest son. While we usually add bubble bath to our bathtub, a bath bomb is also a nice addition. Want to add a little fun to the bath? Check out these DIY LEGO bath bombs for an extra dose of surprise and play time.
DIY LEGO Bath Bombs
These LEGO bath bombs add extra fun to the bath because they reveal a LEGO Minifigure in the center of them. Make these as a surprise for your child or make them together as a fun craft they can enjoy later in the bathtub.
How to make LEGO bath Fizzies
I love to use molds when making DIY bath bombs, sometimes we use a fun shape or simply an ice cube tray to mold our bath fizzie creations. In this case, you will want to use a large round bath bomb molds so that you can hide a LEGO Minifigure inside each bath bomb.
Hide LEGO Minifigure inside bath bombs
Before you get started making the bath bombs, you will want to measure out all the ingredients and prep the Minifigures. Make sure each LEGO Minifigure will fit inside the center of the mold. You may need to bend their legs or adjust their arms to make them fit inside.
LEGO Bath Fizzies Recipe
Thoroughly mix together the citric acid and baking soda. Then very slowly pour in some water and mix with your hands. You want to create a ‘damp sand’ like consistency that will hold together when squeezed.
Scoop up some of the citric acid and baking soda mixture into one half of the mold. Do not pack down yet. Press your LEGO Minifigure into it and then put more mixture on top of the Minifigure. Then fill the other half of the mold with the rest of the mixture and quickly press the two halves together. Try using a slight twisting pressure from both sides to help lock the bath fizzies together.
Remove the LEGO bath bombs from molds
You should be able to carefully and easily remove the molds from the bath fizzies. If it is sticking you can use a wood or silicone spoon to gently tap on the molds to try to help loosen them. Sometimes they stick for no reason and you may need to simply start over. If your mixture is starting to dry a bit you can simply add a *tiny* bit of water to rehydrate. Keep in mind that too much water will cause the mixture to constantly expand and it will never hold a classic bath bomb shape.
Once removed from the mold, allow the fizzies to air dry in a sunny place until completely solid, depending on humidity this may be 24 to 48 hours. They’re done when they seem breakable in a glass way, sound and feel crusty.

Homemade LEGO Bath Fizzies
These would be a fun surprise for you to make for your child. I also think these would make a fun LEGO party favor to give to guests. The birthday child could help you make them up a few days before the party. If you need extra LEGO Minifigures, I recommend buying a bulk set of Minifigs online.
Keep in mind these are best for children who will not put things in there mouth. No one should be eating the bath bomb materials including the LEGO Minifigure.
