Homemade Bath Bombs

Bath bombs are so much and they make for a really cool science experiment. There are so many lessons kids can learn while you make them. It was Kiara’s idea to make these and I am so glad we did, we have a lot of fun mixing them up and even more fun watching them fizz in the bath.

There are so many recipes out there using a different combination of ingredients, I tried to find the simpliest one to start with but I am going to add in different things now that I have a recipe that I know works.

The majority of recipes call for citric soda which was not that easy to find. You find it in the baking isle with the bicarb and baking powders but not every store had it. If you are going to make this then you need to find the little bottle of citric soda, if you can only find the packets, buy at least 6.

We used coconut oil but I think when I do it again I might try our bath oil which has lavender in. If you don’t have coconut oil and don’t want to buy for 2 tablespoons then I am pretty sure you could use olive oil or whatever you have.

When you add the liquids you should here it fizz, if you don’t then you have done something wrong. We did mess up one batch we made when I did it with the kids. I think I added the citric soda for Emma’s mix to Jack’s batch so her’s didn’t fizz and it never set properly (but you can still use it as a bath salt, epsom salts has healing properties).

I have some silicone cupcake moulds that we used, they worked really well but I do think they are a little big.

What do you need:

1 cup bicarb

1/2 cup citric soda

1/2 epsom salts

1/2 cup maizena

2tbsp coconut oil

2tbsp water

Food colouring (optional)

Essential oils (optional)

What do you do:

1. Mix all the dry ingredients together. Make sure there are no lumps.

2. Add the oil and water and then quickly mix it (this is when you will hear it fizz). The mixture needs to start sticking together so you may need to add a few more drops of oil.

3. Add the food colouring and/or essential oil and mix in. If you want to make more than one colour, split the mix into different bowls.

4. Press into moulds and freeze for at least an hour.

5. Watch the magic happen at bath time.

    My oldest daughter loves bath bombs! I really should have her try to make some because they can be so expensive in the stores. This looks like a fun project next time she has a day off of school.

    This would be fun to do at a party for older girls. They could make their own and then they could be favors.

    Oh, this looks so easy and fun. My kids will like this, especially my 3-year-old will love doing this so I can’t wait to try it out. I never knew that bath bombs and salts were actually this simplistic and I love doing new things with the kids.

    We had some issues making bath bombs where they didn’t fizz. It’s fun to make your own at home!
