Jumpscare your friends by telling them to watch the ball, then suddenly the face on the thumbnail pops out and screams! it might take a while between jumpscares, which is good because it makes the anticipation stronger. Try telling your friends to focus hard on the ball, or look at it because something is going to happen. Maybe if your teaching someone else to use scratch you could tell them to watch the ball and think about the code behind how it moves.
Everything by me, but credit for scratch for being so awesome.
