Children learn the science behind the fizz by making their own 100% natural bath fizzies. This kit contains 3 jars of Secret Formula, (a mix of Sodium Bicarbonate, Citric Acid and Corn Starch), 2 bottles of essential oils, safflower oil, witch hazel, and a soap mould. Have fun scenting the secret potion and watching the fizz action when you pour in the pre measured witch hazel and safflower oil. Bath time is so much more fun when children watch their handmade creations fizz around the tub! And they take pride in giving their creations away too.
