Grab something to catch ghosts in! (You can use your hands) First, place your computer somewhere and stand by it (or look around your house.) When you see a ghost, trap it in the object by swooping it on the ghost. The stop button turns video off and resume turns it on.
I just thought of using this to calm a little sibling who is scared of ghosts. You might ask why you get points when the ghost is not there, but he is just super transparent so if you can see him kudos to you. That allows you to get more points if you can see him.
