Review on Playz Chemistry Experiments Reactions Science by Tim Clark

The kit contains 5 ingredients: litmus powder, sodium carbonate, citric acid, potassium ferrocyanide and ammonium ferrous sulfate. They only use the first three, none of the experiments use the other two, and about 2/3 of the experiments consist of baking soda with vinegar, filling balloons with baking soda and vinegar, extinguishing candles with baking soda and vinegar. , baking soda and baking soda, orange juice and baking soda, baking soda and citric acid, etc. Then repeat them all and add the litmus solution to see what color it is. You can find the best science experiments to do at home online, and you don't have to buy a bunch of ingredients you don't even use.
