Geode bath bomb recipe

Bath bombs are all the rage right now, aren't they? In stores that sell baskets and containers full of colorful balls that you toss in the tub to create an incomparable sensory experience in the bathtub. However, they can be costly so we'll roll our own. It's incredibly easy, fun to experiment with what works and what gets the most responses and tailoring them to our needs.

Bath bomb recipe

To do that Bath bomb recipe You will need a few simple supplies that you may already have in your house:

  • Baking soda
  • Cornstarch
  • Epsom salt
  • Food coloring
  • Bath bomb shapes (I used ornaments that can be filled with plastic)
  • Squirt bottle filled with water
  • Optional: essential oils

These bath bombs can be just for fun, but you can also add essential oils for therapeutic reasons, but also for additional sensory experiences. I like to use lavender on my daughter because it helps her sleep and also helps her skin, which is plagued by eczema. If you don't have essential oils or are not in the mood to use them, it won't negatively affect this activity at all.

Geode bath bomb mix

Geode bath bombs

The first step is to add about 2 cups of baking soda to the mixing bowl. Add about half a cup of Epsom salt, 3 tablespoons of cornstarch, and a few drops of food coloring. When adding essential oils, add drops now. I added about 10 drops of lavender. Mix the ingredients with a fork until the food coloring has spread. The food coloring may still be in lumps, but it will spread in the next step.

Use a spray bottle to spray water on the dry mixture. It is important not to get the mixture too saturated. You want just enough water to make the dry ingredients stick together. If you add too much water, the reaction will decrease when the bombs are put in the bath. I start with 5 sprays, mix it completely with the fork and add more sprays if needed. The mixture should clump in your hand, but not be runny.

Divide the fillable ornaments in half and fill each half about ¾ completely with the bath bomb mixture. Press it into the molds until it is all the way down. You want to create a crater type divater in the center of the shape. This will create the look of the geode after the next few steps are added.

Set the bath bombs aside in molds for now.

What is a bath bomb?

How to make geode bath bombs

In separate bowls, add about half a cup of Epsom salt each. I did this in containers that have lids like Tupperware. I also added food coloring to each bowl. I used the same color but different amounts. For example, in the first bowl, I added 4 drops of paint. On the next container I added three and on the last one I only added 1 drop of paint. Put on the lid and shake.

Shake until the paint is completely distributed.

Add a spoon of the darkest color over the bath bombs. I spread this paint all over the surface of the bath bomb. Next, I sprayed a spray of water to bring the Epsom salts into the bath bombs. You can also press on the Epsom salts.

Next I added some of the lighter color, sprayed and squeezed. I repeated this process for the lighter color too. With each color added, I've left a darker ring on the outside.

Set the bath bombs aside and dry them for at least 5-6 hours. I prefer to leave it on for 24 hours, but my daughter has had my sense of patience so we usually use it after 5 or 6 hours. They may still be a little crumbly after the shorter drying time, but the concept can still be seen. The reaction in the bathtub will still take place.

This is the perfect activity to combine with teaching about rocks, volcanoes, or secrets of the world. Geodes are hollow rocks that contain crystals. Not only do they grow this way, there are some strange things that have to happen before these crystals can be created. It's fun recreating our own secret of the world so kids can understand and work firsthand to create their own.
