Editing Electron Tunneling (section)

== Demonstration ==

# Before the demonstration begins, be sure that Presenter A and Presenter B already each have one of the identical balls in a pocket. Have Presenter B set up the box while Presenter A introduces the idea of tunneling through a wall.
# Presenter A only: Ask for a volunteer from the audience, and give the volunteer the tennis ball. Ask the volunteer to try and throw the tennis ball through the wall of the box. Try as they might, the volunteer will fail.
# Presenter A can either ask for a new volunteer for keep the volunteer on stage. Presenter B will now adjust the box so there is only one panel standing, angled so it looks like a thin wall. Presenter A during this time will explain the change to be a way to think of a very thin barrier.
# Have the volunteer now stand with Presenter B. Presenter B will show the audience the small ball and give it to the volunteer, explaining that this will represent an electron.
# Presenter A will now ask the volunteer to throw the small ball at the barrier. Presenter B should whisper to the volunteer to throw it over the barrier. Once it is thrown over, Presenter A will toss it back, explaining how this would have worked.
# Presenter A will not ask the volunteer to throw the small ball one last time. Presenter B should whisper to the volunteer to fake throwing it. When it is "thrown", Presenter A will pretend to "catch" it, and reveal the ball that they had hidden. Presenter B should quickly and secretly hide the ball the volunteer had.
