This is a great trick for some spooky or mentalism shows. You will get a small bottle of this liquid which when applied at the back of the palm will create a burning sensation. We only need a small amount of liquid but it will create a very strong sensation of burning feeling. You can either perform by calling two spectators or by using a voodoo doll. The best part is that the inner part of the palm, fingers will not have any feeling if we apply this. So the magician is not affected by this, so he can take a little amount of liquid in his finger and apply it to the spectators hand while holding his hand without noticing. Also we will get approximately 10 sec delay before the burning sensation starts which give us enough time to get ready for performance. So its a great trick for this money. The bottle is ball headed so no need to squeeze or press the bottle. Just open the lid and roll it across ur finger and you are ready to perform.
