These stripy blue and white bath bombs are fun to make and they will make happy any wizard fans. I’ve used some cosmic and silver mica powder for these bath bombs to add an extra touch of luxury.

This bath bombs recipe is pretty simple and easy to follow, but if you are new to this craft, you can find my step by step guide to bath bomb making on my blog.

Harry Potter Ravenclaw Striped Bath Bombs

Harry Potter Ravenclaw Striped Bath Bombs Supplies Needed

In a large mixing bowl, add the baking soda, citric acid, and cornstarch. Whisk dry ingredients together.

Add essential oils.

Add the coconut oil. This binds all the ingredients together, so you bath bombs don’t crumble when you touch them!

Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub.

Mix the ingredients together. I use my hands to break down any lumps and make sure everything is really mixed in there. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand. Separate mixture into five bowls.

Add 1 tablespoon of the blue mica and blue cosmetic glitter into one of the small bowls and the silver mica and silver cosmetic glitter into the other small bowl. Step 12: Mix colors into mixture thoroughly. Add a bit more color if the mixture is too light. Continue to add a bit and mix until you get the color you want.

Add about 1 tablespoon of your first color into a cavity of one side of the mold. Do the same with the other color and continue until the mold is full. Press both sides of the mold together firmly, grinding together to get rid of the excess mixture. Tap both sides of the mold and gently release the bomb.

Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container until ready for use.
