you get it, but it appears right under you, making you fall in it and not able to move it.

I wish the wheather was always a bright sunny day with a cool wind breeze and at night a bright moon with a breeze.

Granted. There is never any rainfall, causing the Earth's food supplies to run out and a mass extinction.

I wish for a high-end gaming PC.

Granted. But you cannot connect to the Internet, and no games you can play.

I wish nobody will have anything I do not want them to have.

Granted. Everyone hates you, and they launch a nuke at you, killing you.

I wish I could teleport anywhere I wanted.

Deleted

I wish I created the best video game in the universe.

You Create it, but it does't work on any video game console/portable device.

I wish that people had element bending skills, similar to avatar.

Granted. I throw some fire at you and you die pathetically.

I wish that feynman wasn't so mean. :P
