Why forks and spoons? It's always spoons and forks, and hands on them where they can fatigue the metal in front of our very eyes, and then just twist the thing before our very eyes. Never do we see anything bend without hands bending it.
Lay a piece of straw on a table with no draft, and move it a millimeter. That's all it would take. Or, if you want to silence skepticism forever, take a light bulb and use your mind to break the filament inside. Both those things take much less effort than bending a spoon and should be a piece of cake.
Do either of those things with no visible trickery twice in a row and it's game over, and you won't even have to pad out your youtube video with an hour of spiritualist ********.
