i pushed the button. suddenly i fell down right onto a pile of old grass. when i looked around i witnessed an gigantic forest above the river. at that moment i heard a loudy squawk from the heaven. a giant shade covered me completely. i was full of fear and numb horror and the only thing that i could do is just c; osing my eyes tight. when i thought that it was the end, somebody's strong hand grabbed me and pulled back. when i opened my eyes i saw the dark attic and my uncle in face of me. he took me away to the garden behind the house and gave a glass of water. after an hour he made sure that i calmed down and relaxed completely he suddenly clipped on the back of my head. i promised him to keep silence about his invention and never approached to that time-machine again.
