What exactly is an atom? They say it's very tiny but how small is it really? In order to answer these questions about the atom we will conduct two experiments which will enable you to imagine its size.

	Well, the gas got out of the balloon, but why? To answer this question, we will explain here using some illustrations.

	Atoms and molecules are impossible to see with your eyes. However, photos are possible if we use the latest technology. We are going to show you some very rare photos of atoms and molecules.
