To do this activity, get a paper plate and a coin, or try it with any two objects of similar shape. Darling explains:

“Secure the larger circle either by having a friend hold onto it for you, or by using a little bit of tape. Now… take the smaller circle and hold it at arm’s length, and close one eye. See if it overlaps the larger circle.

“If it doesn’t, take a few more steps back and try again until the smaller circle completely overlaps the larger circle.”
