Hello people! I really want to perform this effect. Walk to someone. Ask him/her to think of something and then you read his mind and reveal his/her thought. The person could think of a number, name, something important to him/her, his/her fear, anything at all. No force and no other props. Just a paper and sharpie. I really want to be able to do that effect. The only way I think it's possible is to use spy devices. Any suggestions or comments?
