Magic Tricks

I was super stoked to receive this illusion and when I figured out how it works I thought it was genius, but it doesn't work!! I don't know if the product I received is defective or if all of them are like that, but I spent hours trying to get it to work and the cut wouldn't even disappear. I did everything that Mr. Ran Pink said to and it didn't work. I tried running my hand under hot water for about 5 minutes also and it still didn't disappear.
I haven't tried to do the other affects with this product but considering the main affect didn't work I doubt the other ones will.
