Ike is conducting a scientific experiment involving clear adhesive tape.



He completes each of the following steps:
He removes two strips of tape from the roll.
He presses each strip of tape, sticky-side down, on a plastic surface.
He quickly removes each strip of tape from the plastic surface.
Ike's teacher tells him that this process has caused each strip of tape to gain a negative electric charge. What could Ike do next to demonstrate that the negative charge of each strip has generated an electric field?
