The processes of making Bath Bombs
First Step: Put the baking soda, Epsom salt, corn starch, and citric acid into the large stir bowl. Stir them evenly with the whisk and make sure the mixture is clump-free.
Second Step: After mixing these components together, pour the coconut oil, water, and the food-colorings into the bowl. Then continue to stir them quickly. It also needs to stir evenly. Now, the scent is gradually formed.

The scientific principles of DIY bath bombs
Now, Alpha Science Toys will tell children the secret of bath bombs. The most important components of bath bombs are two kinds of basic materials-acid and base. It’s a basic reaction of acid and base. The baking soda(Sodium bicarbonate) is a weak base and the citric acid is a weak acid. When they meet each other, they can generate carbon dioxide. That is the reason for fizzy when you put the bath bomb into the water. The corn starch is a kind of inhibitor to control the fierce reaction of acid and base. Do you remember the principle of the experiment underwater volcano? In this experiment, citric acid takes place of the vinegar. The dry citric acid does not react with baking soda. That is the principles of bath bombs. Now, do children learn the chemical knowledge of this bath bombs kit?
