Cut through the neck of your spoon with the hacksaw until there is only a thin strip of metal left. Alternately, you can bend the neck of the spoon back and forth many times to weaken it.
Announce to your audience that you are going to use telekinetic powers to bend a normal household spoon.
Bang your altered spoon onto a hard surface to "prove" that it is still intact.
Hold the spoon in your hands so that the handle is pointing down and your thumbs are pressed against the back of the spoon's head.
Push forward with your thumbs to apply light pressure to the back of the spoon. It should move forward easily. Don't push too far or too hard, or your spoon may break.
