The following video shows you a cool magic trick. You need only a matchbox striker. Just watch the video....

Blue bottle Experiment

Hi there. In this post, I'm bring you a really cool experiment. The blue bottle experiment. This is actually not about a blue colored bottle. This is about a color changing solution. There is a bottle contain a liquid like water. When it shake, that liquid turns blue color.
You will need....

1 gram of Sodium hydroxide5 grams of GlucoseMethylene blue Methylene blue is used to treat fungal infections of fish. So you can find it from pet shops. Sodium hydroxide (also called caustic soda) can be found in hardware stores.
Let's start. first mix sodium hydroxide with 20ml of water. Now keep is aside. Then get the glucose and add 40ml of water. 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.

The reason for this color chan…

Do Energy Levels Represents a Length Between Electron and nucleus?

What do you think about that? Niels Bohr said that electrons were travelling in circular orbits. But today, we know that electrons are traveling in orbitals. I think before we answer the question, we have to talk about the structure of electrons.

There are many energy levels in an atom. In each energy level, there are orbitals. There are four types of orbitals, we call s, p, d, f. When we talking about first energy level, there is only one “s” orbital. Then the second energy level, there are two orbitals called “s” and “p”. (I’m only talking about s and p orbitals in this post.) Every electron moving in their orbitals. So, we can’t tell where is the electron at the moment without catching it. But we can mark a specific area (That is what I called orbital.) and tell “the electron can be anywhere in this orbital.” In other words, the possibility of an electron can be

anywhere in orbital is one. By studying their wave function. That specific area is the shape of orbital. So, each orbital …

Chemical Garden

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...
