crossplay

The problem with the crossplay of plastic-based (Mylar) tape is that it's pliable; any difference in temperature or mechanical stress, induced by various transports, will distort track patterns recorded on the compliant tape.

Although in all three events the requests were performed in front of and for the benefit of the student audience as intended bystanders, the crossplay observed in the guest-student episode was absent from the guest-teacher interactions.
