For that you need (for about 48 pieces): 200 g baking soda 200 g of citric acid powder 100 g of Epsom salts 120 ml white vinegar 20 drops of lemon essential oil (optional) 2 or more ice cube shapes First mix soda, citric acid powder and Epsom salts. Next add the white vinegar. By adding it, you will no longer have problems with calcification in the future. If the mixture should hiss a bit, do not worry - it's just a harmless reaction of the vinegar with the baking soda.
