My hobby is collecting and experimenting with chemistry. I wish to become a scientist later. This subject has given me so much but glory for me and my family. Experiments like substances make me curious and want to do it right away. I studied this subject since the age of 6 and it has become one of my hobbies

We’re willing to bet you have seen this one before, but do you know how it works? There are two possible explanations for this illusion. The first is involuntary eye movements; also know as fixation jitter, which explains why the objects next to your point of focus appear to be moving. The second explanation has to do with… you guessed it, your brain. Motion detectors in your brain get confused from the image design and make the motion illusions appear.
