Want to learn how to make bath bombs that look great, smell delicious, and fizz wonderfully? You've come to the right page :-) Get ready for some bubble-licious bath bomb bliss!
There's nothing quite like that feeling when you first immerse yourself in a bath... your muscles relax and the tension fades away in your back and neck. A fizzy bath bomb is the icing on the cake. You drop it in the bath, it bubbles away, and the bath is fragrant with rose or lavender. Bliss!
Learning how to make bath bombs is pretty easy. But I must confess that my first experience was not so successfull. I googled "making bath bombs" or "how to make bath bombs" or something like that. I found some instructions and followed them, but I ended up with a gooey melting mess.
Several batches later, I figured out how to make bath bombs reliably, and now I'd like to share what I've learned :-) You'll be making bath bombs of your own in no time!
No special equipment needed :-)
Don't let the lack of a mold get in the way of learning how to make bath bombs. There are plenty of things that work well as bath bomb molds.
A handy mold for making spherical homemade bath bombs is a two-part, snap-together Christmas decoration. You can find one in a craft stores. Don't worry if you can't get hold of one though, because there are plenty of other things that work just as well.
Chocolate moulds (pictured left) work well, and come in nice shapes like hearts and flowers. You can find them in craft of cookware stores.
There are plenty of other things that work as improvised molds. For round bombs, you can improvise a mold by cutting a tennis ball in half. Other things that work well as molds are muffin trays, ice-cube trays, and shot glasses. Just hunt around your kitchen for a small receptacle of some sort.
In general, smaller bath bombs are easier to make than big ones. Big ones tend to crumble, whereas small ones seem to be more robust.
Now that you've got your mold, here are the other bits and bobs that you'll need. You can find most of these in the supermarket.
Make sure you use a metal or glass mixing bowl rather than a plastic one. Plastic will absorb the smell of the essential oils. That's okay, I guess, but anything you put in the bowl in the future will smell like bubble bath ;-)
Notes: Baking soda can usually be found in the baking section of the supermarket. Baking soda is also called "bicarbonate of soda".
The tablespoon of oil is optional. It gives a lovely moisturising feel. Don't use almond oil though if you or the intended recipient have nut allergies!
To make nice colourful bath bombs, you can mix the basic food colours (red, blue, yellow) to achieve just about any colour you want. Purple is a little tricky. When I mix red and blue, I get... green! But then the bath bomb turns purple once it sets, so all is good :-) Just warning you, so you don't get a surprise!
Wondering what fragrances to use? Take a look at the fragrance blend guide on my essential oil skin care page (ignore the bit about carrier oils - it doesn't apply to bath bombs).
A couple of people have written in to ask where they can buy citric acid. You can sometimes find it in the baking section of the supermarket, but not all stores seem to have it. If you're having a hard time finding it, the easiest place to get it is online, e.g. eBay.
If you really can't find citric acid anywhere, then there is an alternative. One of our readers wrote in with this suggestion for how to make bath bombs using cream of tartar instead:
"I tried the recipe with cream of tartar instead of citric acid, and it works just as well. However, it is quite thick, so half the amount is needed - ie. 2 cups of baking soda, 1/2 a cup of cream of tartar instead of 1 cup citric acid. I hope this is comprehensible and helpful! Keep up the great work!"
You can find cream of tartar in baking section of most supermarkets.
It's a good idea to work in small batches until you get the hang of how to make bath bombs. Scale the recipe down to 1/3 cup of citric acid and 2/3 cup of baking soda at a time. That will still be enough to make two small bath bombs per batch.
Ready? Put on your gloves, and here we go:
My bath bomb crumbles when I try to get it out of the mold!
This could be either because the mixture needs to be compressed more or because it's a little bit too dry. When you put the mixture into the mould, press it in really hard. It can also help to leave it in there a minute or two before you tap it out. If neither of these helps, then try spraying a tiny bit more water on to the mixture.
My bathbomb has turned into an expanding blob!
If your bomb seems to be mysteriously expanding, then you've added too much water and the fizz reaction has already started. You can rescue a too-wet mixture by adding more baking soda and citric acid - two parts baking soda for every one part citric acid. Next time try using less water.
Now that you know how to make bath bombs, I bet you'll be wanting to wrap them up all nice and pretty :-) Here are a couple of ideas:
Wrap your bomb up in tissue paper. For a lavender-scented bomb, a little sprig of lavender makes a nice touch!
