How do you shake your eyes?

It's not an easy thing to explain. You start practicing by looking at your finger or nose right in front of your face. Or you could just go cross eye. If you do this really well and hard you should see a shaking world in double.(Two of everything shaking.)

If this doesn't work for you, you could try this more confusing but more accurate way.

Look left,

Look right,

Look up,

Look down,

Look left with right eye and right with left eye,

Reverse this procedure,

look up with right eye and down with left eye,

Look north then south then east then west and then look left with left eye and right with right eye and after all this, repeat 20 times.

Eyes are now warmed up for shaking.

Go cross eye and the world should start to shake.

I hope this helped, the eye shaker doctor.
