Activity: Ant Analogy!
Imagine yourself as the superhero in a movie entitled "Ant Man". You walk in
a straight rubber sheet, simulating empty space with no mass in it. Walk on one side
of the sheet in a beautiful straight line over to the other side. Then, put a big stone
in the middle of a rubber sheet and walk again (see figure 1 for reference).
