Once upon a time there was a child who was playing in his school's garden when he suddenly found a box in the bushes. He looked around and as he did not see anyone so he decided to open it. Inside he found a very strange round and glass object. He did not know what it was or what it was for but after a while manipulating it he realized that the size of everything he observed through it was magnificent, such as flowers, insects, objects, etc. Finally he decided to tell his classmates and share with them the experience of seeing everything around them at a larger size and thanks to this they described the main characteristics of the insects they found, they cleaned the gardens collecting all the garbage that apparently could not be seen, etc.

While collecting the garbage in the garden, with the help of a magnifying glass the children noticed some invisible iron pieces. Though they had a great difficulty in collecting them, they still did not stop collecting them. Because they wanted the school garden to be clean. A girl named Adelina found a large hard object that looked like a piece of iron. She noticed that the fragments, they could not collect themselves, were gathered on this object and began to examine it. When she tried to collect small pieces, she felt something between them. The small parts and the big object were attracting each other. This looked very entertaining. After trying this a few times, she called her teacher and her friends to show them the funny object she found. She asked her teacher what it was. Her teacher said it was a magnet and the small pieces on it were iron powders. She explained that the magnet has a pulling force, it attracts metal and iron pieces, so iron powders adhere to it. Adelina was very happy to learn it. The teacher said that the garden cleaning was over and they should return to the classroom.
