A bath is even more fun with bath bombs that explode and fizz. It’s easy to make it yourself, in the colors of your choice and even with the fragrance you like. Do you want to add a festive touch? You can even add biodegradable glitters for a sparkling effervescence.
You will need:
From 6 years
Difficulty : medium
Pour the baking soda, Epsom salt, citric acid and cornstarch into the salad bowl.
In a separate bowl, add the sweet almond oil.
Add a few drops of your favorite food coloring and the fragrance of your choice. We have chosen the “Strawberry” fragrance
Very slowly, pour your colored preparation into the bowl while mixing vigorously with the whisk.
Once well mixed, you must obtain a perfectly homogeneous powder in terms of color.
Add the glitter of the color of your choice to finalize your preparation.
Now we make the bath bombs. Using a spoon, fill your mold to form the bomb. Once filled, close them gently and press with all your strength.
Wait a few minutes before releasing the pressure. Carefully remove the mold from above. And let them dry a few hours before moving on to the next one.
Place your bath bomb on a plate and go to the next one.
A few hours of drying later, unmold your bombs and wrap them in the film.
Sparkling bath bombs
In contact with water, you observe tons of bubbles that invade your bath. What is going on? It’s a chemical reaction that takes place around you. On contact with water, baking soda, and citric acid dissolve. In solution, these two reagents meet and react with each other.
Like vinegar, citric acid is what is called an acid. While baking soda is a base. When these two compounds react, they form, among other things, water and carbon dioxide. The bubbles you observe are carbon dioxide which escapes into your bath as your bath bomb dissolves.
It is the same chemical reaction that you observe in the experiment on volcanoes.
