Physics

Recently, I saw a video by Minute Physics and heard a lecture byMichio Kaku about \"How to break the speed of light\". There was abackyard experiment where a person was shooting a strong laser tothe moon's surface from earth and so there was this laser spot onthe moon. Now what he does next is, he flicks his wrist and thespot on the moon moves instantly which implies that the spot on themoon traveled much faster than the speed of light.

Now my question is, since light is made up of photons. When weflick our wrist, new photons are released from the laser torch,(from this new angle we created) which travel all the way to themoon thus creating a new spot. So how is it that the spot on themoon traveled faster than the speed of light? It should have takenthe same amount of time like the first time the laser was shot tothe moon.
