What new plan do the boys devise to get Boo to come out in chapter 5?

The mysterious gifts found in the secret knothole of the old oak tree had aroused the kids' curiOSity to a near breaking point, so Jem decided to take drastic measures in order to lure Boo out into the open. They decided against Dill's suggestion that they knock on Boo's door and invite him for ice cream. Instead, Jem decided he would try using a fishing pole. The children had seen a loose shutter on the Radley house, and Jem figured he would be able to attach a note to the end of the fishing pole and stick it through the shutter. But before Jem could get the note inside, Atticus caught them in the act. He told them in no uncertain terms to "stop tormenting that man."
