Make Your Own Bath Bombs

• Large bowl
• ½ cup citric acid
• 1 cup baking soda
• ½ cup cornstarch
• ½ cup Epsom salt
• Small bowl or glass
• 1 tsp. essential oil
• 1 tsp. water
• 1 tsp. olive oil
• Soap colorant in various colors
• Multiple small bowls
• Small plastic containers 

1. Combine dry ingredients in a large bowl and mix well.

2. Stir wet ingredients together in a small bowl or glass.

3. Very slowly add the wet mixture to the dry mixture and keep mixing! Mix, mix, mix, so it doesn’t fizz and bubble up! After it’s all combined, let your mixture sit for a few minutes. It should feel like wet sand and stay together when you squeeze it in your hand. If it’s still too dry or crumbly, add a drop of water or olive oil—but be careful not to let it get too wet!

  
4. Separate the mixture into smaller bowls and add a drop of soap colorant. Mix well! We found mixing by hand was the most effective way to get an even color. It’s also nice to leave one bowl white for layering.

5. Layer your mixture into molds. We used plastic ornaments split in half and experimented with small plastic containers and other recyclables, like yogurt cups.

6. Pack the layers down tightly into the mold by pressing with your fingers.

7. Let dry for a few minutes before carefully removing the bath bomb from the mold. Don’t try to handle the bath bomb yet! Turn it out from its mold directly onto a surface to dry, and let dry a few hours or overnight.

   
8. Drop in a warm bath and enjoy!
