Exhibition of illusions.

Yesturday Yesterday I visited the exhibition of illusions in the Moscow planetarium with my best friend. The first thing we saw was a painted black sheet of canvas, where which all visitors can could draw or write on with a white pencil. We drew some pictures there and then came to the a video screen.There was two interesting videos playing. One of them is was a test of concentration. You saw how watched people in black clothes and people in white clothes transfer (Transfer is not wrong, but would not usually be used in this context. A better word is pass, which if often used in a sport context, such as "He passed the ball to his team mate) pass the ball and you had to considered count how many times the people in white will transfer passed it. While doing this you don't notice a dancing garilla gorilla in the background. The second video was a test for of your peripheral vision .You consantrate had to concentrate your attention on the point in the between two changing different photos of different celebrities and it seems made them seem ugly.
And There were was also a mirror maze, tilted room and compiled by some rubbish shadow of telescope in the exhibition. (I'm not sure what the part in italics means, if you try to rephrase it, I will have another look) But what struck me most was the dark labyrinth. You feel were blind in there. You must had to go in there to the touch things in absolute darckness darkness. It was really scary! There was a walls covered in the fur, packages and fabrics, some strange ropes hung from the ceiling and toys layed (Wrong word in this context, also, it is spelt laid) laying on the floor. All of this was a horrible, but interesting!!! 

Then we went walking and had a nice day!:)

Very good, I understood almost all of it. The only real problem was that you switched between past and present tense a few times (For example, saying 'We can', instead of 'We could'. If you are telling a story that has already happened, you would usually tell it completely in past tense.

We drew some pictures there and came up to the screen. There were two interesting videos, one of which is concentration test. You could see people in black and in white clothes transferring a ball and you had to keep track of how many times the ball was exchanged. Doing this you don't notice a dancing garilla in the background.
