LET’S MAKE A BATH BOMB!

BATH BOMBS

Running out of ideas how to entertain your kiddos during these home-bound times? Why not do a small chemistry experiment together – an experiment where both of you learn, have fun and the most important part – the parents end up with a delicious and useful treat which they can implement in their self-care routine? Now, let’s make a bath bomb!

FIZZING BATH BOMB

A bath bomb can be made from a wide range of ingredients, including bath salts (such as Epsom salts that can help soothe aching muscles), food colouring, essential oil, glycerol and water. There are, however, a few essential ingredients that most homemade recipes need: baking soda, citric acid and cornflour. The whole idea is, when baking soda and citric acid are mixed and then put in the bathtub water, they undergo a chemical reaction producing lots of fizzy bubbles made of carbon dioxide (CO2) gas. The job of the cornflour is to bind the baking soda and citric acid and slow down the reaction.

LET’S CREATE A BATH-TIME TREAT WITH SOOTHING SALTS & LEMON MYRTLE!

This is how we make our favourite bath bomb:

Ingredients for Bath Bombs.

You also need:

  • Measuring spoons
  • Dropper
  • Spoons for mixing
  • Bowls
  • A muffin tray

PROCEDURE

  1. Mix together all the dry components (baking soda, citric acid, cornflour and Epsom salts) in a bowl.
  2. Then mix up all the wet ingredients (vegetable oil, food colouring, glycerine (or water) and essential oil) in another bowl.
  3. Using a clean medicine dropper, add a few drops of the wet mixture to the dry ingredients in the first bowl. Mix in the wet spot with the rest of the ingredients in the bowl. Repeat this process until you have added, and thoroughly mixed in all of the wet mixture to the dry ingredients. If you are using water instead of glycerol, you will see the mixture fizzing up as soon as you combine the dry and wet mixture. Quickly press down on the fizzy spot with a spoon in order to stop the reaction, as you want to save the reaction for the bath.
  4. The mixture is ready to be placed in the muffin tray, when it’s just like wet sand on the beach that has dried a little bit.
  5. Add a little bit of vegetable oil into each cup on the tray and spread it around using a clean finger.
  6. Fill the tray with the bath bomb mixture using a spoon and remember to squeeze it tight down.  
  7. Now it’s time to let the bath bombs dry. You can either dry the bombs overnight at room temperature or warm them in the oven (preheat the oven to 80C for 30min – turn it off and put the bath bombs in the oven and let them stay there until oven has cooled down.
  8. Once the bath bombs have dried, carefully remove them from the mould.
  9. Now, go put the kids in bed – when they are asleep, pour yourself a glass of red, turn on the hot water in your bath, pop on your favourite face mask, throw in a bath bomb – voila, your self-care routine just got a bit more special. You’re welcome.

QUICK NOTES:

  • You might not need to add all the wet ingredients, if you live in a humid environment. For example – if the bath bomb mixture continues to fizz up when all ingredients have been mixed nicely together, then the mixture may be too wet. Hence, add less water/glycerol next time.
  • If you live in a very dry environment, and your bath bomb ixture is very crumbly, the recipe may need a bit more water.
  • Epson salt tends to consist of big coarse grains, hence it’s a good idea to grind it a bit up, so it gets finer – it will then be easier to work with (and the mixture will stick better together).

Enjoy and have fun making your own bath bomb!
