Optical Illusion

 I completed an Optical Illusion activity. An Optical Illusion is a thing that can make you confuse and trick you.

First, I searched an image on google and I found a bar with four bars but when you see at right there are three bars.

Next, I made a copy of the google drawing and inserted the images.

After, I used two arrows, one at the left and one at the right and I wrote down how many bars there are. 

I like this activity because I want to make someone confused.
