Bath Bombs for Kids That Will Make You Win at Bath Time

My mom always told me that giving my kids a bath in the evening will calm them down. A warm bath will relax them and help them sleep.

These are lies, by the way.

My kids equate bath time to a day at a water park. They get a burst of energy during a bath that flows over to our bedtime routine.

They choose bath time to practice cannonballs and see how effective the side of the tub is as a makeshift water slide. Once out of the bath, there is usually barely time to get a towel around them before they are running through the house dripping wet and literally bouncing off the furniture.

Does this sound like bath time at anyone else’s house or are our kids abnormal?

One thing that my kids love during a bath is using fizzy bath bombs, so I decided to make a batch just for them.
  • 1 c. baking soda
  • 1/2 c. citric acid
  • 1/2 c. cornstarch
  • 1/4 c. Epsom salt
  • 2 tbsp oil of choice {olive, fractioned coconut, almond all work}
  • 1/2 tsp. essential oil
  • food coloring {optional}
  • 1-2 tsp water as needed
  • bath bomb mold
Combine the dry ingredients {baking soda, citric acid, corn starch, and Epsom salt} in a large bowl and mix well.  

Citric acid is used in food canning and can be found in most grocery stores or bought in bulk online.  I stumbled upon a bunch of containers of citric acid marked down 90% at my grocery store and they were having an extra 50% off the lowest price.  Needless to say, I stocked up.
Combine oil, essential oil, and food coloring in a separate bowl and slowly add to the dry ingredients.
You want the mixture to feel like damp sand that will clump together when you squeeze it. If it is not clumping, add a small amount of water and keep mixing.  Repeat until you get the texture you are looking for.

The amount of water you need will vary depending on factors such as humidity and whether you are using other water based products (like food coloring).  It’s very important to add a little water at a time.  If you get too much moisture, it will feel like dough and it will start to expand in the mold.  If this happens, break the mixture back up in your bowl and mix in more corn starch.
I used jumbo sized plastic Easter eggs and it made 5 bath bombs. You can also use bath bomb molds or even a meat baller.  Lightly oil your mold or dust with corn starch to avoid the mixture sticking as it dries {I speak from experience – I had to dig a couple of our bath bombs out with a spoon}.

Pack the mixture firmly into the mold. Let it dry for 24 hours in the mold.  Gently work the Easter egg off of your bath bomb and they are ready for use.
These would have been a great addition to their Easter basket, but I decided to let my boys try them out early since the anticipation was killing them.

They were really excited to see if their bath bomb would float or sink {it sank}, fizz or not {it fizzed}, and whether the bath water would change colors {it got cloudy but the food coloring didn’t change the color of the water and didn’t stain their skin or the tub}.  They were mesmerized by the bath bomb fizzing around and love to see what happens when they put it under running water or catch it in their toy boat.

Using the Lavender bath bombs for kids definitely made for a more interesting bath.  They were so into it, in fact, that they forgot all about their usual cannonball practice.

    We inserted the crayola bath tabs into the eggs so that the bath water will turn colors. Excited to take them out of their “shells” tomorrow and see how it all worked out!

    "These are lies, by the way." So funny and true!
