Place the newspaper on a flat surface and stand the plastic film canister on top of it. In the canister, draw two circles using a pencil; one circle should be an inch above the bottom, and the other circle, an inch below the top. Cut two strips of duct tape lengthwise. One of them should wrap the drawn circle on top, and the other for the bottom circle. Place the copper wire at the bottom and continue to wrap upward. Do this process twice. Solder the end of the copper wire to the pins in the white LED, and put the LED inside the canister. Drop two magnets and close the lid. Shake the canister so that the LED will be lit.
