Let's experiment

pour the powders into the container

Pour the baking soda, Epsom salt, citric acid and cornstarch into the salad bowl.

sweet almond oil spoon

In a separate bowl, add the sweet almond oil.

introduce the food coloring

Add a few drops of your favorite food coloring and the fragrance (essential oil) of your choice. We have chosen the “Strawberry” fragrance

pour the colored liquid

Very slowly, pour your colored liquid 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.

mix the preparation
bath bomb mold

Now we make the bombs. Using a spoon, fill your mold. Pack well with your fingers. Once filled, close them gently and press with all your strength.

unmoulding the bath bombs

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 ball on a baking sheet in a dry place.

After a few hours of drying, unmould your bath balls. To keep them longer, wrap them in cling film.

Now you can enjoy the pleasure of a relaxing and explosive bath, with a cosmetic product that you have prepared yourself.

The manufacture of bath bombs

So you’ve made bath bombs. Test them immediately in your bathtub. When the water comes into contact with them, you see tons of bubbles invade your bath. It’s an effervescence. What’s going on? It’s a chemical reaction happening around you. When they come into contact with water, baking soda and citric acid become soluble. In solution, these two salts meet and react with each other. Like vinegar, citric acid is what we call an acid. Baking soda is a base. When these two compounds react, they form, among other things, water and carbon dioxide. The bubbles you see are made of carbon dioxide. This is what escapes as your bath bomb dissolves. This is the same chemical reaction you see in the volcano experiment. You can make more in the scent of your choice. Lavender, Ylang Ylang, grapefruit, rosemary… anything goes.

Yeast’s inflating power

Here is a great and visual experience for you to discover the secret world of bacteria. They are very useful to us and we use them in many cooking recipes, for example. Watch how bacteria turn sugar into alcohol and carbon dioxide using a simple soda bottle and a balloon.
It’s a great way to identify which drinks have sugar and which doesn’t. […]
