DIY Harry Potter Bath Bombs

My daughter recently started reading the series and asked for a Harry Potter birthday party. As you can imagine, I can’t wait to start planning it. We’ve decided one of the party favors will be a Golden Snitch bath bomb! Keep reading for 6 DIY bath bomb ideas and the recipe at the bottom of the post.

Quick video tutorial on how to make bath bombs

Harry Potter Hogwarts House Bath Bombs

When I started planning the Harry Potter inspired bath bombs, I knew I wanted to incorporate a couple of the Hogwarts Houses. There are four houses at Hogwarts School of Witchcraft and Wizardry. I chose Gryffindor and Slytherin, the two most notable houses potter fans associate with. Of course, you could easily create Hufflepuff and Ravenclaw in coordinating colors.

Gryffindor Bath Bomb

The Gryffindor bath bomb is made with layers of maroon and gold bath bomb mix. We made ours in a Butterbeer scent (butterscotch). This would make a great handmade gift idea for Harry Potter fans!

Slytherin Bath Bomb

Ah, the infamous Slytherin House. Where many dark wizards come from, but also one of my personal favorites – Severus Snape. J.K. Rowling has said that Snape was a complicated, flawed character. His story is so heartbreaking that you can’t help but adore him in the end. The Slytherin Bath Bomb is made with layers of green and silver in a peppermint scent. It’s hard to tell in photos, however, I used a small amount of grey and black mica cosmetic powder to create the silver layer. This can also be made with grey gel dye.

Quidditch Golden Snitch Bath Bomb

The iconic Hogwarts game of Quidditch inspired this Golden Snitch bath bomb covered in gold cosmetic mica powder. To make it you will lightly spray your bath bomb with isopropyl alcohol and roll it in gold glitter. This will create a sparkly golden snitch ball that will turn your bath water into shimmery gold.

HP Logo Bath Bomb

If you have any leftover mix use it to make a round bath bomb with a stenciled HP logo on top. To make one you will need to let it dry overnight before removing from the mold. Find a Harry Potter logo online to print and cut or use your electronic cutter. I sized mine to about 2.25 inches (note: the cut logo shown was too big, I ended up cutting a small logo out using my Silhouette). If you have amazing painting skills, then skip the cutting and hand paint it on. To paint the logo, combine a splash of isopropyl alcohol with a small pinch of black cosmetic mica powder in a small disposable cup. Place your cut logo on top and use a small brush to stencil the HP logo on. I used a similar method to make these Panda Bear cuties.

Lightning Bolt

This bath bomb was made using a lightning bolt icing decoration. To make them you will place the lightning bolt inside the mold then press your mixture in and allow it to dry overnight. You can find the Lightning Bolt Icing Decorations HERE. The plastic rectangular mold is from the craft store in the soap section.

Butterbeer Bath Bomb

The classic wizarding butterscotch drink from the book series inspired these Butterbeer Bath Bombs. I shared these last week but had to include them in this collection. If you’ve never tried the drink before, the drink is made with crème soda and Butterscotch flavors topped with whipped cream. It can be served cold, frozen or warm. We personally like the Frozen Butterbeer the best! To make a bath bomb inspired by the drink I made a layered bronze and gold bath bomb infused with butterscotch fragrance oil.

DIY Harry Potter Bath Bombs

How to make Harry Potter inspired bath bombs

Ingredients

• 1 cup baking soda
• 1/2 cup citric acid
• 1/2 cup epsom salt
• 1/2 cup cornstarch
• 2 tbsp grapeseed oil
• 3/4 tsp water
• 1 tsp butterscotch oil

Instructions

1. In a large bowl, combine baking soda, citric acid, cornstarch and Epsom salt. Separate mixture into two bowls.

2. Combine grapeseed oil, water and fragrance in a small cup.

3. Add cosmetic mica powder to each dry mixture bowl. Start at about ½ tsp and increase until desired color is reached. Note: the mixture will darken once the liquid is added.

4. Evenly divide liquid into each bowl while stirring to avoid activating the bath bomb mixture.

5. Layer the mix into the mold and firmly press together. Dry overnight before removing from molds.

6. Wrap or store in a dry, cool place.

Notes:

• You can substitute the grapeseed oil for almond oil or coconut oil.
• This recipe makes 3 medium size bath bombs. I created the entire collection by making a large batch and separating the mixture into small bowls. I also did this over time – not on the same day. Pick your favorites or make all 6 but know that the mixture can create around 3-6 bath bombs, depending on the size of the mold. It was definitely a labor of love and one I’m so happy to share with you guys. After sharing bath bomb recipes for years, I love thinking of new ideas.
