Have you ever dreamed of being like magician David Copperfield? Well, this is start.
This is a classic magic trick.
First, you need to get a matchbox and tear off the striker strip. Then fold the strip in half and place it in an ashtray or non-flammable surface and set it on fire.
After discarding the charred striker strip, what you’ll be left with is a yellow or brown residue. Wipe off the residue with your fingertip, rub your fingers together and voilà!
WARNING: The residue can be harmful to your health, so it is important that you wash your hands immediately after the awesome effect is over.
