                        Activity: Create a Simple Paper Circuit

                        1.  Use a small battery, some copper tape, and an LED.

                        2.   Connect the copper tape to both ends of the battery and the LED to make it
                           glow.

                        How to complete: Stick the copper tape on paper, connect it to the battery and
                        the LED, and watch the light glow when the circuit is closed.
