Look through these forward and reverse videos. The first one is the most interesting, because all the actions are in reverse but there are short stretches in the video where you can't really tell which way it is going. The other two go in forward and reverse but only show one action in more detail. For the parts, which are "obviously" in reverse and "not so easy to tell", think about which features alert you to whether something is being played forwards or in reverse.

The videos showed cases where it was quite clear at some point that you were watching something in reverse. Try to think of some examples where it would be very hard to tell, or even impossible to tell if a video was being played forwards or in reverse.
