Bubble chemistryYou little wannabe chemists wanna know all about it? Here's how it works…When you keep your bath ball dry, nothing happens. When it takes the plunge, it creates an acid-base reaction due to the presence of two friendly ingredients: citric acid + sodium bicarbonate = Fizz!!! Indeed: carbon dioxide is released with a profusion of bath happy balls. This remarquable bubbling duo is totally biodegradable and non toxic. Sodium bicarbonate has been in the cosmetic spotlight for a while now (because it's worth it) and its natural fellow citric acid can be found in many veggies such as lemon. All in all a pleasant company for kid's bath. Dermatologically tested to protect sensitive little skins.Recyclable packaging printed using vegetable ink. To be used under adult supervision.
