Describe the atmosphere in the auditorium.

Students are outside the auditorium, checking membership cards to make sure that only Wave members are allowed in for the rally. Inside the gym, the students spontaneously begin to chant The Wave’s mottoes as Alex and Carl set up the film on the projector. Meanwhile, David and Laurie try to enter the gym but the doors are locked. They are able to slip in during the confusion that ensues after a student gets angry that the televised address hasn’t come on yet. All of the students are becoming impatient.
