OH YEAH FACTS: The gun from Nintendo's Duck Hunt doesn't actually shoot anything; it is a light receiver.
When you pull the trigger, the screen goes black for a split second, and then a white shaped duck appears over the black. The gun is just a sensor for a change in light (from black to white) so if it’s pointed where the duck is, it’ll pick up the black screen and then the white duck.
Early…
Best. Game. Ever.
