Now add few drops from Methylene blue and mix the solution. And now pour the those two solutions to a volumetric flask. If you don't have a flask, just get a bottle. After few seconds the solution turns colorless. Now shake the flask. It turns blue and again after few seconds, it turns colorless. Just enjoy. Th

            When I was 10yeas old, I read a book about funny experiments. Among every other experiments, there was a experiment about chemical garden. However I couldn't did it, because I haven't any idea about using chemicals. and also I had no way to find chemicals. By the January of this year I could gather some chemicals to do this experiment. I learned how to make sodium silicate at home. Then I got a chance to do this experiment.             In this experiment we are using some colorful salts to make our garden colorful. However I could use only three salts. They were copper sulfate, zinc sulfate and ferrous sulfate. I wanted to use nickel sulfate. But I failed to make them. Ok. Let's see what we need... The experiment processed in a test tube You will need :- A Beaker (or any other clear glass container) Sodium Silicate (Water glass) Water (Distilled water is better) Some kinds of salts( copper sulfate, ferrous sulfate, etc.)            Color of yo
